Question: Please define/ differentiate glycogenesis, glycogenolysis and gluconeogenesis ? Edit
Answer: Glycogenesis is the process of glycogen formation from glucose. The process depends on body's demand for glucose and ATP. If they are present in high quantity then the insulin helps to enhance the glucose conversion into glycogen for storage in muscles and liver.
Glycogenolysis is the process in which the glycogen stored in muscles and liver gets converted into glucose-1- phosphate first and then into glucose-6-phosphate. The process is controlled by glucagon secreted from pancreas and epinephrine from adrenal glands.
Gluconeogenesis is the process of glucose synthesis from non-carbohydrate sources. Lactic acid, glycerol from fat and certain amino acids from protein are converted into glucose. Edit
