BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Glucagon triggers your liver to convert stored glucose (glycogen) into a usable form and then release it into your bloodstream. This process is called glycogenolysis. Glucagon can also prevent your liver from taking in and storing glucose so that more glucose stays in your blood.

Detailed explanation-2: -Glucagon is a glucoregulatory peptide hormone that counteracts the actions of insulin by stimulating hepatic glucose production and thereby increases blood glucose levels.

Detailed explanation-3: -After a meal, glucose enters the liver and levels of blood glucose rise. This excess glucose is dealt with by glycogenesis in which the liver converts glucose into glycogen for storage. The glucose that is not stored is used to produce energy by a process called glycolysis.

Detailed explanation-4: -Glucagon’s role in the body is to prevent blood glucose levels dropping too low. To do this, it acts on the liver in several ways: It stimulates the conversion of stored glycogen (stored in the liver) to glucose, which can be released into the bloodstream. This process is called glycogenolysis.

Detailed explanation-5: -When glucose is in your bloodstream, cells throughout your body can use it for energy. The glycogen stores in your liver also partially help with muscle activity and exercise. At the start of exercise, your liver begins breaking down glycogen to maintain blood glucose levels as your working muscles use it for energy.
