Question

Which regulatory molecule increases anabolism in muscle after exercise training? There is one correct answer.

A. glucagon
B. insulin-like growth factor
C. myostatin
D. cortisol

Answer 1

The regulatory molecule that increases anabolism in muscle after exercise training is insulin-like growth factor (IGF-1).

Step-by-step explanation:

The regulatory molecule that increases anabolism in muscle after exercise training is insulin-like growth factor (IGF-1).

Growth hormone (GH) directly accelerates the rate of protein synthesis in skeletal muscle and bones. This activation of GH leads to the production and activation of IGF-1, which supports the formation of new proteins in muscle cells and bone.

Therefore, the correct answer is insulin-like growth factor (IGF-1).
