Insulin is a hormone secreted by our pancreas in response to an increase in blood sugar. Insulin interacts with the cells in our body to help move excess glucose from the blood into the liver, muscles, and fat tissue.
Insulin can interact with cells to allow glucose to be used as energy or stored. Liver converts glucose into glycogen to be used for future use. The liver can hold about 100 grams of glycogen. Just like the liver, skeletal muscles convert glucose into glycogen and can store about 400 grams. Lastly, when the liver and muscles are full, the liver converts the remaining glucose into triglycerides which are stored in fat tissues.
