1. Lipids to ATP * Hydrolysis is the first step in the breakdown of lipids. This happens in the cytoplasm, to produce fatty acids and glycerol. The glycerol is then metabolized into dihydroxyacetone phosphate. This hydroxyacetone is further metabolized into one of two compounds: pyruvic acid (for energy) or glucose-6-phosphate (during gluconeogenesis). * Fatty acids are catabolized into Acetyl Coenzyme-A, during something called the fatty acid spiral, which is then transformed into ATP, carbon dioxide, and water using the electron transport chain and the citric acid cycle. * ATP is created from both the citric acid cycle and the fatty acid spiral (Brandt, n.d.). 2. Saturated vs Unsaturated fatty acids * Saturated fatty acids: carbons are single bonded, solid at room temperature * Unsaturated fatty acids: carbons are double bonded, liquid at room temperature (Fatty Acid, 2015)

1. Saturated Fatty Acid

2. Unsaturated Fatty Acid

3.

4. No-Fat Diets * Non-fat diets are detrimental to the body, because vitamin-D, an essential vitamin, cannot be absorbed without lipids (fats). Vitamin D is essential to the absorption of vitamin C and phosphate. Vitamin C and phosphate are necessary for bone structure, neuromuscular function, and immune function. * Lipids are also necessary for the absorption of estrogen, one of the hormones responsible for reproduction, related to fetal growth and uterine changes during pregnancy. Without fat in the diet, pregnancy is not possible (Lichtenstein & Van Horn, n.d.).

...Task 5 A. Jenny is looking for the best option for daycare for her son. She lives in a small town, so her options are limited to two daycare centers. Option A is a home-based facility which charges $9.00 per hour that the child is at the home. Option B is a center-based facility which charges $150 for the first 20 hours and then charges $10 per hour thereafter. Due to a new promotion, Jenny will be required to work more hours away from home. Which facility will cost less for Jenny to have her son in daycare for a work week (40 hours)? B. I. h = how many hours of child care is needed = 40 f = the flat hourly rate charge t = total amount due for the week Option A: f * h = t a. 9 * 40 = $360 Option B: 150 + f(h-20) = t, for h >=20 b. 150 + 10(40-20) = $350 150 = t, for h < 20 c. 150 = total II. I set the hours to "h", the hourly fee to "f" and the total to "t". a. Option A: This option only has an hourly fee for each hour. The fee is $9 and the amount of hours is 40 so I multiplied the hours by the fee. b. Option B: This option has a flat rate of $150 for the first 20 hours and then an hourly rate of $10 thereafter. For the first equation that refers to over 20 hours, I subtracted 20 hours from the total time, multiplied it by $10, and then added it to $150. For the second equation that refers to any amount less than 20 hours, the total is always......

Biochem Task 5 Wgu

...Biochemistry: Task 5 Christi Corder 000356780 November 1, 2015 A.  There are three sources of fatty acids in the body. One of these sources is adipose tissue, in which adipose tissues release tissue fatty acids. Another source is the liver, which makes fatty acids, which travel through the bloodstream. Dietary fat is also a source. Three stages are involved in the breakdown of fatty acids to produce ATP. These are beta oxidation, the citric acid cycle, and the electron transport chain. A fatty acid is a long chain of carbons and hydrogens with a carboxylic acid group at the end. In beta oxidation, the fatty acid is broken down into two carbon units, which produce acetyl-CoA, and electrons and hydrogens are removed. The first step of beta oxidation occurs when the fatty acid is activated by the addition of a CoA subunit and the fatty acid is broken down into carbon units called acetyl-CoA and electrons and hydrogens are removed. The electrons and hydrogens are carried by NADH and FADH-2 to the electron transport chain and are used to make ATP. NADH and FADH-2 are also produced during the CAC and these also enter the electron transport chain and are used to produce ATP from ADP and inorganic phosphate. Also, the hydrogens from NADH and FADH-2 combine with oxygen and the electrons to form water. (O’malley, 2014). B.  One difference between saturated and unsaturated fatty acids is that saturated fatty acids have as many hydrogens as can possibly fit around......

Biochemistry Grt1 Task 5 Lipids

...Biochemistry Task 5- Lipids Student ID# Western Governors University 05/21/2015 Biochemistry Task 5- Lipids A. Fat is stored in the body and used as an energy source when not enough energy is available from food. This process involves dismantling the stored fat in fat cells and releasing the components into the bloodstream. The major storage form of fats in our body are triglycerides, which are made up of three fatty acids bound to glycerol. Adipocytes are primary cells that store fat in the triglyceride form. White adipose cells are used to store energy (O’Malley, M. 2014). 1. Triglycerides are the storage molecules that are broken down and used to produce ATP. The triglycerides break down into two different items, glycerol and fatty acids. The triglycerides are formed when glycerol binds to three fatty acid molecules. The fatty acids each break down into 2 carbon parts. Each part of the carbon makes Acetyl CoA. The Acetyl CoA molecule then enters the Citric Acid Cycle before it moves on to the next step, the electron transport chain. The end result of each of these steps is the production of 12 ATP (Hudon-Miller, 2012). B. 1. Saturated fats do not contain a carbon-carbon double bond. Unsaturated fats contain at least on carbon-carbon double bond. The saturated fatty acid chains can stack while the unsaturated fatty acid chains are kinked by the double bond. 2. Saturated fats have a high melting point and are solid at room......

...A. Explain how lipids, in the form of triglycerides, are broken down to produce ATP, including ​each​ of the following: Triglycerides are first broken down to fatty acids and glycerol by separating the bond between the glycerol and the fatty acid. The fatty acids undergo beta oxidation and are broken into two carbon units. The carbon subunits generate Acetyl­CoA. (O’Malley 2014) During beta oxidation hydrogen and electrons are removed from the fatty acids and are carried by NADH and FADH2 to the electron transport chain to generate ATP. Acetyl­CoA enters the citric acid cycle which removes electrons and hydrogen. NADH and FADH2 is used to carry the ions to the electron transport chain to form ATP. B. Explain two differences between saturated and unsaturated ​fatty acids​ (not fats). A saturated fatty acids has hydrogen on all points of its chemical chain. Unsaturated fatty acids will have a pair of hydrogen missing on its chain. Saturated fats are solid at room temperature vs liquid for unsaturated. 1. Create ​one​ original 3­D model to demonstrate the chemical structure of a saturated fatty acid. 2. Create one original 3­D model to demonstrate the chemical structure of an unsaturated fatty acid.

... Biochemistry Task 4 09/05/2015 1. Describe two important features that make all enzymes ​catalysts​. A catalyst is a substance which can accelerate the rate of a chemical reaction without going through a chemical change itself. Enzymes are proteins which help accelerate the rate of reactions. Enzymes also lower activation energy without being used. (Hudon­Miller 2012) After and enzyme and substrate bind it converts the substrate to it’s specific product. The enzyme remains unchanged and it is free to move on to other products as the enzyme itself does not undergo a chemical change during this process. 2. Create an original diagram, or series of diagrams, with clear labels, that demonstrates the entire enzymatic cycle described by the lock and key model OR the induced fit model. 3. Create an original diagram, or series of diagrams, with clear labels, that illustrates the activation energy of a reaction in the presence and absence of an enzyme. 4.

Biochemistry Task 5 Lipids

...Biochemistry Task 5 Lipids A. Adipose tissue stores fat in the body. The fat storage molecule is called a triglyceride. Triglycerides are composed of a glycerol attached to three fatty acids. In order to use a triglyceride for energy, the fatty acids are broken away from the glycerol. These fatty acids are considered free fatty acids. Free fatty acids are broken down, two carbons at a time by beta oxidation. Each two carbon unit becomes Acetyl CoA, which then enters the citric acid cycle. Also, during beta oxidation there are electrons and hydrogens that are removed from fatty acid. They are carried by NADH and FADH2 to the electron transport chain. They are used to form ATP from ADP and a phosphate. B. There are two types of fatty acids, saturated fatty acid and unsaturated fatty acid. Saturated fatty acids are saturated with hydrogen, meaning all the carbons in the chain are filled with hydrogen. Saturated fatty acid chains all look similar which makes it easy for them to build on one another. The force that holds them together is known as hydrophobic interactions. This allows fatty acids to be solid at room temperature. Saturated fatty acids are mainly from animal food sources. Unsaturated fatty acids will not be saturated with hydrogen, instead there is a double bond that lessens the amount of hydrogen in a chain. This double bond bends the tail and the structure becomes irregular. This irregularity doesn’t allow them to stack well, therefore unsaturated fatty......

Wgu Biochemistry Task 3

...WGU Biochemistry Task 3 A1) There are several differences between the oxygenated and deoxygenated states of hemoglobin. One difference can be seen in the conformational state of the hemoglobin protein. When oxygenated, the protein takes on the T (tense) state; and when deoxygenated, the protein takes on the R (relaxed) state (Hudon-Miller, 2012b). Another difference arises when oxygen binds to the hemoglobin, resulting in a change in the shape of the protein. In the deoxygenated state, the heme group forms a domed shape; and in the oxygenated state, the heme group takes on a planar shape (Hudon-Miller, 2012b). A2) The relationship between pH and the ability of hemoglobin to bind and release oxygen is referred to as the Bohr Effect. The blood’s pH level is greatly influenced by the carbon dioxide that is produced by most of the body’s cells during the citric cycle (Hudon-Miller, 2012d). Greater CO2 concentration lowers the blood’s pH level, making it more acidic. In turn, lower CO2 concentration increases the blood’s pH level, making it more basic. Since the lungs function involves breathing in oxygen and blowing out carbon dioxide, the lungs are absolutely crucial in maintaining the pH balance that the blood requires (Hudon-Miller, 2012d). While in the lungs, the hemoglobin becomes saturated with oxygen and slowly delivers it to the body’s tissues as it travels through the bloodstream. At the same time, the hemoglobin is also picking up the carbon dioxide that is......

Biochemistry Task 5

...Biochemistry Task 5 March 6, 2016 A. Triglycerides are the main make up of body fat in animals and humans as well as vegetable fat. Triglycerides are made up of glycerol and three fatty acids. Fats or lipids as a whole are not bad for you as they are used for energy, always in moderation, but there are different types of fats that you do need. Your body utilizes saturated fat very fast as opposed to other fats that has to go through different stages to be used. Triglycerides in food are digested and are processed in the liver combining it with a protein and then travel through your blood stream to your cells where they are then used for energy. Glycerol enters into the pathway through the Pyruvate and then onto Acetyl-CoA where it enters the Cori-cycle. From there it is transported to the electron transport chain where the end product is ATP. ATP is the body’s energy. Through beta oxidation fatty acids enters the pathway through the Acetyl-CoA. From here it moves the Cori cycle where they are then broken down into sugars and transported to the electron transport chain where ATP is the end product. Low fat diets are dangerous in that they strip the body of the process of this breakdown. Reduces energy stops the breakdown of fat for use in the digestive system gallbladder and liver. With this reduction the decrease of bile also stops the production of CCK or Cholecystokinin which signals the pancreas to release bile to breakdown the lipids. Simply the product will be...

The four forces that stabilize a protein. * Hydrophobic interactions which are interactions by nonpolar amino acids. The weakest of the four types of bonds. * Hydrogen bond made up of interactions of polar or charged amino acids. The amino acids share their hydrogen. This is also a weak bond, but it is stronger than the hydrophobic interaction. * Ionic bonds are made up of charged amino acids. A positive charge of an amino acid attracts to a negative charge of another amino acid. This bond is a little stronger than the hydrogen bond, but not as strong as the polypeptide bond. * Disulfide bond only occurs between two cysteine amino acids.

...Task 4: Metabolism 1. They speed up reactions and do not change themselves, which means they can be used over and over. Enzymes help facilitate chemical reactions. Enzymes will lower the activation energy needed to start the reaction and that is how the reaction will be sped up. Enzymes are specific for certain reactions and are proteins. Not all catalysts though are enzymes. (Sanders, 2014) 2. (Gresham HS IB Biology, 2007) 3. (Hudon-Miller, S. 2012) 4 & 5. When table sugar is consumed, it is broken down into glucose and fructose. Glucose is used in the blood stream. Glucose can be stored in the liver as glycogen. Fructose does enter glycolysis, but first two steps are original to fructose. The first step involves breaking down fructose into fructose-1 phosphate by the enzyme, fructokinase. Fructose is the substrate of fructokinase and it’s product is fructose-1 phosphate. Fructose-1 phosphate is converted into DHAP and glyceraldehyde (products), by the enzyme aldolase B which will enter the glycolysis pathway. (Hudon-Miller, S. 2012) In HFI, there is an aldolase deficiency, so there is no conversion of fructose-1 phosphate into DHAP and glyceraldehyde, so they do not enter the glycolysis pathway to produce ATP or in gluconeogenesis. The fructose is still achieving phosphorylation by fructokinase, which results in a build up of fructose-1 phosphate. The liver cells are unable to utilze fructose as energy. There becomes an abundant buildup of......
