Question

 

Lipogenesis, or fatty acid synthesis, occurs in several cycles. A diagram of the reactions of the first cycle fatty acid synthesis is shown below.

 

Which of the following statements are true? Select all the true statements.

Answer 1

a. In fatty acid synthesis, each cycle lengthen the fatty acid chain by three carbon atoms -------> FALSE

b. In lipogenesis, acetyl and acyl molecules are activated by an acyl carrier protein (ACP) ---------> TRUE

C. Acetyl-SCoA is used to produce malonyl-SCoA --------> TRUE (carboxylation reaction)

d. The first cycle of lipogenesis yields CO2, 1 NADP+, and an acyl group attach to ACP -----------> FALSE (The first cycle of lipogenesis yields CO2, 2NADP+, and an acyl group attach to ACP).

e. Malonyl CoA adds a two-carbon group to the growing fatty acid chain with each cycle ----------> TRUE

f. The reactions of lipogenesis include, but are not limited to, condensation, reduction, and dehydration ------> TRUE
