11

Rapid uptake or release of glucose

GLUT 2

12

the rate-limiting step in the utilization of glucose in extrahepatic tissues

uptake from the bloodstream

13

___ cells are freely permeable to glucose in either
direction (via the GLUT 2 transporter)

Liver.

Cells of extrahepatic tissues (apart from pancreatic β-islets) are relatively impermeable, and their unidirectional glucose transporters are regulated by insulin.

14

The β-islet cells are freely permeable
to glucose via what glucose transporter?

GLUT 2

15

Glucose transporter with dual function (uptake and release)

GLUT 2
