Which of the following statements about fatty acid synthase is false?
A. Acyl carrier protein catalyzes the condensation reaction between acetyl and malonyl groups to form acetoacetyl-ACP.
B. The palmitoyl thioesterase (TE) domain is responsible for cleaving palmitoyl-ACP into free palmitate.
C. The reactions catalyzed by fatty acid synthase are analogous to those of fatty acid oxidation but they occur in the reverse direction and are catalyzed by a single enzyme.
D. The enoyl-ACP reductase (ER) site of fatty acid synthase converts a substrate with a trans αβ double bond into a product that is fully saturated.
Please provide why.
