GLUT-1 and GLUT-2 Overview

Text: “Types of Glucose Transporters (GLUT)” Narration: “Different tissues

express different glucose transporters, each adapted to specific physiological functions.”

Label: “GLUT-1 – High affinity transporter” Narration: “GLUT-1 is present in red blood cells

and the blood–brain barrier. It has a high affinity for glucose and ensures continuous

glucose supply, especially to the brain, even at low blood glucose levels.”

Label: “GLUT-2 – Low affinity, high capacity” Narration: “GLUT-2 is found

in hepatocytes, pancreatic beta cells, renal tubular cells, and intestinal epithelium.

It is a low-affinity, high-capacity transporter and allows bidirectional movement of glucose, playing a key role
