A scientist is trying to design a drug to modulate cellular metabolism in the treatment of obesity. Specifically, he is interested in understanding how fats are processed in adipocytes in response to different energy states. His target is a protein within these cells that catalyzes catabolism of an energy source. The products of this reaction are subsequently used in gluconeogenesis or β-oxidation. Which of the following is true of the most likely protein that is being studied by this scientist?
AIt is stimulated by epinephrine
BIt is inhibited by glucagon
CIt is inhibited by acetylcholine
DIt is inhibited by cortisol
EIt is stimulated by insulin
