Step-by-step solution
Glucagon stimulates the liver to convert stored glycogen into glucose. Glucagon is also called an "anti-insulin" hormone. Insulin is antagonistic to glucagon. Insulin converts glucose into glycogen in the liver and muscles. It promotes protein synthesis in tissue from amino acids.Insulin reduces catabolism of proteins. It is an anabolic hormone. It increase the synthesis of fat in the adipose tissue from fatty acids. Insulin reduces the breakdown and oxidation of fat.
