Write answer in between .Q: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 ß-oxidation. Which of the following is true of the most likely protein that is being studied by this scientist?? A: It is inhibited by acetylcholine, B: It is inhibited by cortisol, C: It is inhibited by glucagon, D: It is stimulated by epinephrine, E: It is stimulated by insulin,  <response>: This is a question about cellular metabolism and enzyme regulation in adipocytes fat cells. The scientist is interested in a protein that catalyzes the breakdown of an energy source, and the products are used in gluconeogenesis or beta-oxidation. Based on this information, the protein is likely involved in the breakdown of triglycerides fats into fatty acids and glycerol. The fatty acids can then undergo beta-oxidation to generate acetyl-CoA, which can feed into the TCA cycle and gluconeogenesis pathways. The question asks which statement about the regulation of this proteinenzyme is true. We need to consider which hormones and signals might stimulate or inhibit the breakdown of triglycerides and fatty acid oxidation.D: It is stimulated by epinephrine
