Which of the following is the MAIN mechanism by which insulin promotes muscle growth?

Increasing amino acid uptake and protein synthesis (correct)

Stimulating glycogen synthesis

Enhancing glucose uptake by muscle cells

Inhibiting lipolysis and promoting fatty acid synthesis

How does insulin inhibit the process of lipolysis?

By stimulating the breakdown of triglycerides into fatty acids and glycerol
