After a meal the blood sugar level will be elevated due to the absorption of sugars from the digestive tract. These cells then release the glucose into your bloodstream so your other cells can use it for energy. This involves many hormones, including insulin and glucagon that regulate cellular glucose uptake as well as glucose storage and endogenous glucose production [85, 215]. It regulates glucose concentrations in the blood. glucose as the primary fuel for the brain and signaling a reduction in protein Glycogen is mainly stored in the liver and the muscles and provides the body with a readily available source of energy if blood glucose levels decrease. Insulin works in tandem with glucagon, another hormone produced by the pancreas. In these scenarios, glucagon tells your liver and muscle cells to break down stored glycogen back into glucose. If a persons body cannot maintain this balance, diabetes and other conditions can result. Glucagon interacts with the liver to increase blood sugar, while insulin reduces blood sugar by helping the cells use glucose. Liver cells then remove more glucose from the blood and store it.
