ANATOMY

Detailed explanation-1: -Glucagon helps blood glucose levels rise back up in multiple ways, including: Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream.

Detailed explanation-2: -The insulin tells cells throughout your body to take in glucose from your bloodstream. As the glucose moves into your cells, your blood glucose levels go down. Some cells use glucose as energy.

Detailed explanation-3: -Like a key fits into a lock, insulin binds to receptors on the cell’s surface, causing GLUT4 molecules to come to the cell’s surface. As their name implies, glucose transporter proteins act as vehicles to ferry glucose inside the cell.

Detailed explanation-4: -Insulin is a peptide hormone secreted by the cells of the pancreatic islets of Langerhans and maintains normal blood glucose levels by facilitating cellular glucose uptake, regulating carbohydrate, lipid and protein metabolism and promoting cell division and growth through its mitogenic effects.

Detailed explanation-5: -After you eat, carbohydrates break down into glucose, a sugar that is the body’s primary source of energy. Glucose then enters the bloodstream. The pancreas responds by producing insulin, which allows glucose to enter the body’s cells to provide energy.
