BioChem C785 - WGU - Module 5 - all questions
A patient who is on a no-fat diet is at particular risk of deficiency in: - ✔✔Vitamin A
Acetyl-CoA is a central to metabolism. Carbohydrates, proteins, and fats can all produce Acetyl-CoA,
though they use different pathways to make it. - ✔✔True
Acetyl-CoA, a central molecule in metabolism, is produced in the mitochondrial matrix. However, it is
used for the synthesis of fatty acids in the cytosol. The transport of the acetyl-CoA from the matrix to
the cytosol occurs by the conversion of acetyl-CoA to - ✔✔citrate
Beta oxidation of a C14 fatty acid will make 6 acetyl-CoA units after 7 rounds of beta-oxidation - ✔✔True
CH3(CH2)6CH=CH(CH2)2COOH - ✔✔liquid at the lowest temperature
Describe the steps involved in fatty acid synthesis - ✔✔Acetyl-CoA is transported to the cytoplasm -
Biotin transfers a carboxylate group to acetyl-CoA - the malonyl group is transferred to a carrier protein -
malonyl ACP combines with acetyl-CoA, - malonyl-CoA is added repeatedly to the growing fatty acid
Due to their amphipathic nature, phospholipids can form micelles and transport other lipids. The fatty
acid chains that make up the phospholipids are the basis for their non-polar character, and the
phosphate group is the basis of its polar nature - ✔✔True
During starvation, triglycerides can help supply some of the body's glucose needs. Which breakdown
product of triglycerides can be used to make glucose? - ✔✔glycerol
Fats are necessary to deliver the fat-soluable vitamins such as A, D, E, and K. Absence of fat in the diet
impact the absorption and delivery of the fat soluable vitamins that result in vitamin related
deficiencies. - ✔✔True
Fatty acid synthesis occurs in the cytosol, so its building block molecule acetyl-CoA must be transported
out of the mitochondria and into the cytosol using the citrate transport system. The acetyl-CoA is then
