Insulin binding to the insulin receptor activates a that act

Insulin binding to the insulin receptor activates a that activates glycogen synthase and deactivates glycogen phosphorylase.

Solution

Insulin binding to the insulin receptor activates a tyrosine kinase that activates glycogen synthase and deactivates glycogen phosphorylase.

Insulin receptors when bound with insulin, activates tyrosine kinase which phosphorylates substrate proteins which leads to an increase in the high affinity glucose transporter (Glut4) molecules on the outer membrane of insulin-responsive tissues, including muscle cells and adipose tissue, and therefore to an increase in the uptake of glucose from blood into these tissues.
