What hormone is responsible for facilitating glucose uptake in liver, muscle, and adipose tissues?

Insulin is the hormone primarily responsible for facilitating glucose uptake in liver, muscle, and adipose tissues. Produced by the pancreas, insulin promotes the transport of glucose from the bloodstream into these tissues, where it can be used for energy or stored for future use. When blood sugar levels rise after eating, insulin secretion increases, allowing cells to absorb glucose efficiently.

In muscle tissue, insulin enhances the recruitment of glucose transporters to the cell membrane, increasing glucose uptake. In the liver, insulin stimulates the conversion of glucose to glycogen, promoting energy storage. In adipose tissue, insulin facilitates the uptake of glucose as well as the synthesis of fat, contributing to lipid stores. This coordinated action of insulin helps maintain normal blood sugar levels and regulates energy metabolism in the body.
