Question

Indicate whether the following statements are true or false. Justify your answer.

a. ( 3 pts) _____ Acetyl- CoA carboxylase is activated by palmitoyl- CoA.

b. (3 pts) ______ During the synthesis of palmitate in liver cells, the addition of malonyl-

CoA to fatty acid synthase elongates the growing chain by three carbons.

         c. ( 3 pts) ______ Lipoprotein lipase is an intracellular enzyme.

Answer 1

Ans a) False.

Acetyl CoA carboxylase is activated by citrate and it is inhibited by phosphorylation whereas palmitoyl CoA exerts control within the cell.

b) False.

During the synthesis of palmitate in liver cells, the addition of malonyl-CoA to fatty acid synthase elongates the growing chain by two carbons.

c) False

It is an extracellular enzyme present on the surface of vascular endothelial that degenerate circulating triglyceride in the stream of blood.
