Question

the effect of insulin on the glucose transport is to
1)Permit transport against a concentration gradient
2)enhance transport into adipocytes
3)enhance transport across the tubular epithelium of the kidney
4)enhance transport through intestinal mucosa
​

Answer 1

Explanation:

Insulin acts by increasing the glucose transport rate of each transporter, by increasing the number of functional glucose transporters, or by a combination of both mechanisms. Insulin resistance in adipose cells is associated with a decrease in GLUT4 transporter number and activity.

Answer 2

Answer:

GLUT1 is insulin-independent and is widely distributed in different tissues. GLUT4 is insulin-dependent and is responsible for the majority of glucose transport into muscle and adipose cells in anabolic conditions.
