Insulin Synthesis and Secretion

Nettet14. apr. 2024 · Insulin is a hormone secreted by the pancreas that it is responsible for controlling blood sugar levels. Insulin helps glucose enter the body’s cells so that it can be used for energy. As glucose enters your body’s cells, glucose levels in the bloodstream decrease. Insulin also signals to the liver to store glucose for later use.
