Carrier is permanently in … WebWhile glucose in the bloodstream can reach all body cells, it can't enter them--entering cells requires crossing a cell membrane, which glucose can't do on its own. Glucose from the bloodstream enters cells with the help of two proteins. The first, explains Dr. Sherwood, is called a glucose transporter, or GLUT protein.
