HUMAN NUTRITION

Detailed explanation-1: -After meals, glucose is stored as glycogen in the liver. During fasting periods, glucose is released from glycogen (glycogenolysis) becoming available to be used in other tissues.

Detailed explanation-2: -A main function of glycogen is to maintain a physiological blood glucose concentration, but only liver glycogen directly contributes to release of glucose into the blood.

Detailed explanation-3: -In response to the same, the pancreas secretes insulin. This activates the hepatocytes of the liver to secrete glycogen synthase. It polymerises the glucose to glycogen. So, the liver takes more glucose from the blood in order to convert it into glycogen and store it in the liver.

Detailed explanation-4: -Glycogen is stored in the liver. When the body needs more energy, certain proteins called enzymes break down glycogen into glucose. They send the glucose out into the body.
