WebApr 9, 2024 · Step 1. The first step in glycolysis (Figure 7.2. 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. WebYou may be familiar with this process from products like sauerkraut and yogurt. The chemical reaction of lactic acid fermentation is the following: Pyruvate + NADH ↔ lactic acid + NAD+. Figure 1. Lactic acid fermentation converts pyruvate (a slightly oxidized carbon compound) to lactic acid. In the process, NADH is oxidized to form NAD+.
