BIOL 221 Lecture Notes - Lecture 9: Glycogenolysis, Glycogenesis, Gluconeogenesis
Document Summary
Gluconeogenesis is the formation of glucose from glycerol (from triglycerides) or amino acids (after conversion to glyceraldehyde-3- phosphate). Glycogenesis is the formation of glycogen from glucose. This process is used to store glucose in the liver and skeletal muscle. Glycogenolysis is the process by which glycogen is broken down into glucose. In the liver the glucose can be released to maintain plasma glucose levels between meals. Review your notes from this topic and from a&p i. Lipogenesis is the formation of lipids from glycerol and fatty acids. stimulate. Glucose and amino acids can be converted either into glycerol or into acetyl-coa. Acetyl-coa can be used to make nonessential fatty acids. Glucose absorbed is either used for energy or stored as glycogen or converted to triglycerides. Amino acids are used for protein synthesis. During the postabsorptive state glucose levels are maintained by gluconeogenesis and glycogenolysis in the liver, which then releases the glucose into the blood.
