Q

What is glycogen?

A

Glycogen is a source of energy for the body. It is comprised of glucose molecules. It is a polysaccharide. Removes water through glycolysis to create glycogen. Glycogen forms an energy reserve.

Q

What is the second function of insulin?

A

Starts glycogenolysis, stimulates lipogenesis –> stores in adipose tissue
Stimulates lipoproteins –> allow fats to move about in the bloodstream
(Absorptive state)

Q

What is the third function of insulin?

A

Glucagon is released from pancreas when the blood sugar gets too low
Gluconeogenesis starts when you have no more sugar to feed your brain
(Rest absorptive)
