Glycogenesis and Glycogenolysis (BIOCHEMISTRY)

  1. 1. Glycogenesis & Glycogenolysis _________________________ CHRISTIAN JAY RAYON NOB BACHELOR OF SCIENCE IN MARINE BIOLOGY MINDANAO STATE UNIVERSITY @ NAAWAN CAMPUS
  2. 2. Glycogenesis:  Glycogenesis is the formation of glycogen from glucose. Glycogen is synthesized depending on the demand for glucose and ATP (energy). If both are present in relatively high amounts, then the excess of insulin promotes the glucose conversion into glycogen for storage in liver and muscle cells.  In the synthesis of glycogen, one ATP is required per glucose incorporated into the polymeric branched structure of glycogen. actually, glucose-6-phosphate is the cross-roads compound. Glucose-6-phosphate is synthesized directly from glucose or as the end product of gluconeogenesis.
  3. 3. Glycogenolysis:  In glycogenolysis, glycogen stored in the liver and muscles, is converted first to glucose-1- phosphate and then into glucose- 6-phosphate. Two hormones which control glycogenolysis are a peptide, glucagon from the pancreas and epinephrine from the adrenal glands.  Glucagon is released from the pancreas in response to low blood glucose and epinephrine is released in response to a threat or stress. Both hormones act upon enzymes to stimulate glycogen phosphorylase to begin glycogenolysis and inhibit glycogen synthetase (to stop glycogenesis).

  5. 5. Glycogenesis &Glycogenolysis  involved in the regulation of glucose concentration  when dietary intake of glucose exceeds immediate needs, humans and other animals can convert the excess to glycogen, which is stored in either the liver or muscle tissue. Glycogenesis is the pathway that converts glucose into glycogen
  6. 6. Glycogenesis &Glycogenolysis  when there’s need for additional blood glucose, glycogen is hydrolyzed and released into bloodstream. Glycogenolysis is the pathway that hydrolyzes glycogen to glucose  when intake of glucose exceeds immediate needs and the capacity to store glycogen, the excess can be converted into fat which can be stored in unlimited quantity
