Textbook Question
Chapter 37.5, Problem 1TYK
Insulin primarily regulates blood glucose concentrations by
- stimulating the recruitment of glucose transporter proteins from the cytosol to the plasma membrane for transport of glucose from extracellular to intracellular fluid.
- stimulating gluconeogenesis.
- suppressing glucose uptake by muscle tissue.
- stimulating the release of glucose from glycogen reserves in the liver.
- inhibiting the synthesis of new GLUT proteins.
