Answer 1

Protein kinase a, which stimulates glycogen degradation, is activated directly bym cyclic AMP.

What is glycogen?

• Animals, fungi, and bacteria all use the multibranched polysaccharide of glucose known as glycogen to store energy.
• The primary form of glucose storage in the body is represented by the polysaccharide structure.
• Our cells primarily use glucose as fuel.
• The liver and muscles store the glucose when the body doesn't need to use it for energy.
• Glycogen is the name given to this form of glucose that is stored and is composed of several linked glucose molecules.
• Although only liver glycogen directly contributes to the release of glucose into the circulation, maintaining a healthy blood glucose concentration is one of glycogen's key functions.
• The body uses glycogen as a major energy reserve.
• For instance, liver glycogen controls homeostasis and blood sugar levels.
• On the other hand, muscle glycogen aids in physical exercise by allowing skeletal muscles to contract.
