Question

Quizplus · Accepted Answer

The signaling molecules activated by the insulin-tyrosine kinase second messenger system facilitate the insertion of glucose carrier proteins into the plasma membrane, which increases glucose uptake by the cells. This is the primary mechanism by which insulin regulates blood glucose levels. Hydrolysis of glycogen and secretion of glucose are mediated by other hormone signaling pathways such as glucagon and cortisol. Transport of insulin into the cell is not a function of the insulin-tyrosine kinase second messenger system, but rather the process by which insulin binds to its receptor on the cell surface and initiates the signaling cascade.
