Question

A major function of the insulin signaling pathway is to promote the translocation of the glucose transporter, GLUT2, from intracellular vesicles to the plasma membrane. True or false?

A) True
B) False

Answer 1

The major function of the insulin signaling pathway is to promote the translocation of the glucose transporter, GLUT2, from intracellular vesicles to the plasma membrane, facilitating glucose uptake into body cells.

Step-by-step explanation:

The major function of the insulin signaling pathway is indeed to promote the translocation of the glucose transporter, GLUT2, from intracellular vesicles to the plasma membrane. This allows for the uptake of glucose into body cells. Insulin activates a tyrosine kinase receptor, triggering multiple biochemical reactions that result in the movement of intracellular vesicles containing GLUT2 to the cell membrane. Once on the cell membrane, the glucose transporters facilitate the movement of glucose into the cell through facilitated diffusion.
