During short-term starvation, most available fuel molecules are catabolized to provide energy for metabolism rather than being used as building blocks for growth and repair, a trade-off that is hormonally regulated by
A) acetylcholine.
B) glucagon.
C) oxytocin.
D) antidiuretic hormone.
E) insulin.

Question

Quizplus · Accepted Answer

Glucagon is the hormone responsible for promoting the breakdown of glycogen and the conversion of other molecules, such as fats and amino acids, into glucose for energy production during short-term starvation.
