WebMar 13, 2024 · Glycolysis is the process by which one molecule of glucose is converted into two molecules of pyruvate, two hydrogen ions and two molecules of water. Through this process, the 'high energy' intermediate molecules of ATP and NADH are synthesised. Pyruvate molecules then proceed to the link reaction, where acetyl-coA is produced. … WebGlycogenolysis The process of liberating glucose from glycogen is known as glycogenolysis.

"WebGlycogenesis is the process of storing excess glucose for use by the body at a later time. Glycogenolysis occurs when the body, which prefers glucose as an energy source, needs energy. The glycogen previously stored by the liver is broken down to glucose and dispersed throughout the body. " - Describe the process of glycogenolysis
