Question

The presence of insulin allows insulin-sensitive cells to take up glucose through the action of:

a. insulin receptors.
b. glucagon.
c. glucose transporters.
d. diffusion.

Answer 1

Insulin triggers the movement of glucose transporters to the cell membrane, allowing glucose uptake by cells.

Step-by-step explanation:

Insulin triggers the rapid movement of glucose transporter vesicles to the cell membrane, where they fuse and expose the glucose transporters to the extracellular fluid. The transporters then move glucose by facilitated diffusion into the cell interior. This process is facilitated by insulin receptors and glucose transporters.
