Question

Which property is not associated with acetyl-CoA carboxylase? O biotin functioning as a cofactor O catalysis of an irreversible reaction O production of oxaloacetate O production of malony!-Co Fatty acid synthase l of mammals_ o consists of two polypeptide chains: one with three enzymatic activities, the other with four O is a homodimer complexed with an additional polypeptide chain known as acyl carrier protein O is a single polypeptide chain in its fully functional form O uses malonyl-CoA to add two-carbon units to a growing fatty acid chain enzymatic activities Which factor is not associated with biosynthesis of palmitate? O O O O production of 14 NADP* hydrolysis of seven ATP consumption of a total of eight acetyl-CoA production of eight H2O

Explanation / Answer

1. Option C is correct.
Acetyl CoA carboxylase is a biotin-dependent enzyme that catalyzes the following irreversible reaction.
Acetyl CoA + HCO3- + ATP ----> Malonyl CoA + ADP + Pi

2. Option D is correct.
Fatty acid synthase I of mammals uses malonyl CoA to add two carbon units to the growing fatty acid chain.

3. Option D is correct.
Biosynthesis of palmitate.
8 Acetyl CoA + 14 NADPH + 7 ATP ----> Palmitate + 14 NADP+ + 7 ADP + 7 Pi
