In Studies with a Particular Cell Line in Culture You

In studies with a particular cell line in culture you discover that the rate of mitochondrial fatty acid oxidation increases when the cells are stimulated to increase their rate of de novo fatty acid synthesis. This observation is quite unexpected since these 2 processes do not normally coincide. Which of the following enzymes involved in fatty acid synthesis is most likely to be altered thus, allowing for fat oxidation to be enhanced along with an increase in fat synthesis?

A) acetyl-CoA carboxylase 2
B) ATP-citrate lyase
C) fatty acid synthase
D) malic enzyme
E) steroyl-CoA desaturase
