Which group is similar to the "business end" of CoA in acyl carrier protein?

Question

Quizplus · Accepted Answer

The "business end" of CoA in acyl carrier protein is the phosphopantetheine arm, which attaches the acyl group during fatty acid synthesis. Biotin is involved in carboxylation reactions, phosphoadenosine is a component of ATP, and pyridoxal phosphate is a cofactor for many enzymes involved in amino acid metabolism. Therefore, the group that is most similar to the phosphopantetheine arm is D, as both are involved in carrying and transferring acyl groups in various biological processes.
