Question

GLUT-4 is

• A. a protein which enables glucose transport in cells.
• B. a carbohydrate which enables glucose transport in cells.
• C. a protein which enables glutathione transport.
• D. a lipid which allows transport of hormone.

Answer 1

Answer: (A)

Glucose transporter type 4 (GLUT-4) is a protein that facilitates glucose transport across membrane in cells.
GLUT4 is the insulin-regulated glucose transporter. It is primarily found in adipose tissues and striated muscle (skeletal and cardiac). GLUT-4 is a insulin-regulated glucose transporter that permits facilitated diffusion of blood glucose down its concentration gradient.
