B) fatty acid synthase
C) hormone-sensitive lipase
D) acetyl CoA carboxylase
E) ATP-citrate lyase

Question

Quizplus · Accepted Answer

During exercise, the body requires energy, and the hormone-sensitive lipase enzyme is activated, breaking down stored fat into fatty acids to be used as a source of energy. Glycogen synthase, fatty acid synthase, acetyl CoA carboxylase, and ATP-citrate lyase are all involved in the synthesis or storage of energy molecules, which is not the focus of the exercise response.
