WebIn glycolysis, Substrate-Level Phosphorylation is the transfer of a phosphate group from a 3 carbon organic molecule to ADP. This reconstitutes ATP which can be used in other important energy consuming processes of the cell. Substrate-Level Phosphorylation is different from Oxidative Phosphorylation which will be discussed in Step 12.

WebStep 1. The first step in glycolysis (Figure 9.1.1) is catalyzed by hexokinase, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates glucose using ATP as the source of the phosphate, producing glucose-6-phosphate, a more reactive form of glucose. WebGlycogenesis and glycogenolysis are reciprocally regulated. The two opposing, regulated enzymes are glycogen synthase (glycogenesis) and glycogen phosphorylase (glycogenolysis). Each is regulated by phosphorylation/dephosphorylation and by binding of other molecules. Phosphorylation of glycogen synthase switches it to the inactive, or "b " …
