Glycogenolysis Overview & Process What is Glycogenolysis

WebThe first step in glycolysis is catalyzed by hexokinase, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates (adds a phosphate to) glucose using ATP as the source of the phosphate ( Figure 2 ). This produces glucose-6-phosphate, a more chemically reactive form of glucose. WebApr 16, 2024 · Glycogenolysis occurs mostly in the liver and muscle cells.
