Question

Which of the following is induced by insulin?

a. Mobilization of vesicle docking molecules.
b. Generation of GLUT transport vesicles.
c. Activation of a transmembrane receptor.
d. Incorporation of GLUT-4 proteins into the cell membrane.
e. All of the above.

Answer 1

Insulin induces the incorporation of GLUT-4 proteins into the cell membrane, allowing glucose uptake.

Step-by-step explanation:

Insulin induces the incorporation of GLUT-4 proteins into the cell membrane.

Insulin triggers a cascade of events in the cell that leads to the fusion of GLUT-4-containing vesicles with the plasma membrane. This allows glucose transporters to be exposed on the cell surface and facilitate the uptake of glucose into the cell. Therefore, the correct answer is d. Incorporation of GLUT-4 proteins into the cell membrane.
