WebJan 22, 2024 · Glycolysis produces two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water. Glycolysis takes place in the cytoplasm. … WebThe 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. shutters outside mount
