How does glycogen enter glycolysis
WebGlycogen Synthesis. The liver is a so-called "altruistic" organ, which releases glucose into the blood to meet tissue need. Glucose released from muscle glycogen stores is used on site to provide energy for muscle contraction. Like glycolysis and gluconeogenesis, glycogenolysis and glycogenesis are NOT reversals of each other. WebExpert Answer Ans 1 When blood sugar levels drop, glycogen is broken down into glucose -1-phosphate, which is then converted to glucose-6-phosphate and enters glycolysis for ATP production.
