The pancreas responds by producing insulin, which allows glucose to enter the body's cells to provide energy. Store excess glucose for energy. After you eat — when insulin levels are high — excess glucose is stored in the liver in the form of glycogen.

What does insulin do to blood sugar levels?

When you take insulin, it helps to move glucose out of your bloodstream and into cells. Your cells use some of that sugar for energy and then store any leftover sugar in your fat, muscles, and liver for later. Once the sugar moves into your cells, your blood glucose level should go back to normal.

What are three functions of insulin?

Insulin is an anabolic hormone that promotes glucose uptake, glycogenesis, lipogenesis, and protein synthesis of skeletal muscle and fat tissue through the tyrosine kinase receptor pathway.
