Explanation: 

Detailed explanation-1: -Diabetes occurs when the pancreas, a gland behind the stomach, does not produce enough of the hormone insulin, or the body cannot use insulin properly. Insulin helps carry sugar from the bloodstream into the cells. Once inside the cells, sugar is converted into energy for immediate use or stored for the future.

Detailed explanation-2: -Type 1 diabetes occurs when the pancreas does not make enough, or any, insulin. Without this hormone, the cells cannot get enough energy from food.

Detailed explanation-3: -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-4: -When blood glucose levels fall too low (low blood glucose), the pancreas pumps out more glucagon. This hormone helps blood glucose rise back up in multiple ways: It causes the liver to convert stored glucose into a usable form and then release it into the bloodstream. (A process called glycogenolysis.)
