HUMAN NUTRITION

Detailed explanation-1: -The glycogen stores in your liver also partially help with muscle activity and exercise. At the start of exercise, your liver begins breaking down glycogen to maintain blood glucose levels as your working muscles use it for energy. However, your muscles primarily use their own glycogen stores to function.

Detailed explanation-2: -Major changes in metabolism are known to occur as the glycogen supply dwindles; when glycogen storage in the liver is depleted, stored adipose tissue triglycerides are released into the circulation as fatty acids and glycerol.
