Before a fatty acid can undergo B-oxidation it must be: O Transport of the FA into the mito. matrix O Hydrolysis of the carboxyl group from the FA O Carboxylation of Acetyl-CoA to form malonyl-CoA Activation of the FA with Coenzyme A O Oxidation of the FA yielding a A2-enoyl intermediate
Which of the following statements is TRUE about cholesterol biosynthesis? O NADH is needed to form mevalonate. O HMG-CoA lyase catalyzes the committed step. Six molecules of isopentyl pyrophosphate condense to form squalene. O Cholesterol is composed of 30 carbon atoms.
Fatty acid synthesis requires the activation of acetyl CoA to malonyl CoA. However, its condensation with a fatty acyl ACP results in the addition of only its two carbons. What is the thermodynamic advantage of the activation reaction? . The condensing enzyme requires a 3-carbon compound as substrate. Cleavage of CO2 from malonyl CoA provides the energy to allow for condensation to occur. It is the activate form of the two carbon acetyl CoA necessary for condensation. It makes malonyl CoA unstable. The reaction is a reversal of the 2-oxidation which is a spontaneous process.
Part A Identify each of the following metabolic pathways. Drag the appropriate labels to their respective targets. Reset Help the conversion of fatty acids to 2-carbon units of acetyl CoA ketogenesis the conversion of an amino acid to an a-keto transamination acid the combination of 2-carbon units of acetyl COA to form fatty acids oxidative deamination the removal of an amino group as NH4+ from B oxidation glutamate to yield a-ketoglutarate lipogenesis the production of ketone bodies
Fatty acids are activated for breakdown through the action of acyl-CoA synthestase. Which of the following statements regarding acyl-CoA synthetase is not true? ● It catalyzes the addition of CoA to the fatty acid One of the products of the reaction is ADP. O The free energy change for the reaction catalyzed by this reaction is close to 0 kJ/mol, but the subsequent hydrolysis of pyrophosphate drives the reaction forward. O The reaction results in the formation of a thioester bond.
