Insulin is a hormone that regulates glucose levels, allowing the body's cells to absorb and use glucose. Without it, glucose cannot enter the cell and therefore cannot be used as fuel for the body's functions. [128]
Ball-and-stick model of a glucose molecule. Blood sugar regulation is the process by which the levels of blood sugar, the common name for glucose dissolved in blood plasma, are maintained by the body within a narrow range. The regulation of glucose levels through Homeostasis. This tight regulation is referred to as glucose homeostasis.
Liver glycogen stores serve as a store of glucose for use throughout the body, particularly the central nervous system. [4] The human brain consumes approximately 60% of blood glucose in fasted, sedentary individuals. [4] Glycogen is an analogue of starch, a glucose polymer that functions as energy storage in plants.
Glucose can be transported from the intestines or liver to other tissues in the body via the bloodstream. [2] Cellular glucose uptake is primarily regulated by insulin, a hormone produced in the pancreas. [2] Once inside the cell, the glucose can now act as an energy source as it undergoes the process of glycolysis.
The researchers used hyperglycemic clamp and oral glucose tolerance tests to examine the participant’s beta-cell function and insulin release at the beginning and end of the 12-week diet period.
Glucagon in the liver stimulates glycogenolysis when the blood glucose is lowered, known as hypoglycemia. [12] The glycogen in the liver can function as a backup source of glucose between meals. [2] Liver glycogen mainly serves the central nervous system. Adrenaline stimulates the breakdown of glycogen in the skeletal muscle during exercise. [12]
