Web13 aug. 2024 · If no oxygen is present, then NADH builds up and the cell can run completely out of NAD. Without NAD glycolysis stops. NAD becomes a "limiting reagent" The chemical whose concentration determines whether the reaction will happen or not. In the absence of Oxygen, the cell runs out of NAD and glycolysis is stopped until it can be regenerated. WebThe reactants are pyruvate, NADH and a proton. The products are lactate and NAD +. The process of fermentation results in the reduction of pyruvate to form lactic acid and the oxidation of NADH to form NAD +. Electrons from NADH and a proton are used to reduce pyruvate into lactate. icaew cipfa mergerWeb3 jan. 2024 · Two NADH molecules provide energy to convert pyruvate into lactic acid.
