Question

Quizplus · Accepted Answer

Cortisol is the primary hormone involved in protein breakdown in the postabsorptive state. It stimulates the breakdown of proteins and inhibits their synthesis, which helps provide amino acids for gluconeogenesis and energy production during fasting or starvation. Glucagon is also involved in protein breakdown, but its primary role is to stimulate glycogenolysis and gluconeogenesis in the liver. Epinephrine and thyroid hormone have minor roles in protein metabolism.
