Insulin receptors

Insulin receptors are specialized proteins located on the surface of certain cells, such as those in muscles and fat tissue. They act like locks that recognize and bind to insulin, a hormone released after eating. When insulin attaches to these receptors, it triggers a series of signals inside the cell that promote the uptake of glucose (sugar) from the blood. This process helps regulate blood sugar levels, providing energy for the body and maintaining metabolic balance. Proper functioning of insulin receptors is essential for healthy blood sugar control and overall metabolism.
