The insulin receptor (violet) is a transmembrane protein, that is activated by insulin (light green). Insulin binding induces structural changes within the receptor. These changes trigger a biochemical chain of events inside the cell, (signal transduction) that finally leads to the activation of the glucose transporter protein (orange), which transports the glucose (yellow) molecules into the cell.

Insulin is a protein hormone that regulates the metabolism of carbohydrates and fats through the assimilation of glucose from the blood in the skeletal muscles and fat tissue. Dsplay styles: ball and stick, ribbon, line and molecular surface . Source; PDB entry 3I40.

Red blood cells and white blood cells are two types of blood cells that play different roles in the body, including within arteries. Arteries are blood vessels that carry oxygen-rich blood away from the heart to various parts of the body. In the context of arteries, both red and white blood cells travel through them as part of the circulatory system. Red blood cells carry oxygen from the lungs to the body's tissues, including the cells within the arterial walls. White blood cells can also move through arteries, as they are essential for monitoring the bloodstream for potential threats and responding to infections or inflammation.
