Homework Answers
The end product of fatty acid synthesis by mammalian fatty acid synthase complex is Palmitate.
Palmitate is produced from acetyl Co A and Malonyl Co A in the presence of NADPH
Hence option C is correct.

1. Which of the following is true? a. The main rate-limiting step for fatty acid breakdown is the transfer of the fatty acyl group to carnitine, with release of CoA. b. Elongase activity is an enzyme functionality of fatty acid synthase that adds 2-carbon acetyl groups to increase the length of palmitate. c. Oligomycin directly inhibits Complex I in the electron transport chain d. Squalene synthase catalyzes the rate-limiting step of fatty acid synthesis.
