Detailed explanation-1: -Insulin helps control blood glucose levels by signaling the liver and muscle and fat cells to take in glucose from the blood. Insulin, therefore, helps cells to take in glucose to be used for energy. If the body has sufficient energy, insulin signals the liver to take up excess glucose and store it as glycogen.

Detailed explanation-2: -After you’ve eaten, the concentration of glucose in your blood rises. When it goes too high the pancreas releases insulin into the bloodstream. This insulin stimulates the liver to convert the blood glucose into glycogen for storage.

Detailed explanation-3: -High insulin levels are representative of an overall positive energy balance (eating too much). If excess glucose isn’t used, it’s converted into glycogen and stored in the liver, muscle, and brain cells.

Detailed explanation-4: -During a meal, insulin stimulates glucose storage by the liver as glycogen. The insulin released from the liver acts on adipose and muscle tissue to stimulate glucose uptake.

Detailed explanation-5: -Glucose is the main source of fuel for our cells. When the body doesn’t need to use the glucose for energy, it stores it in the liver and muscles. This stored form of glucose is made up of many connected glucose molecules and is called glycogen.
