Figure 1 Lactic acid fermentation is common in muscles that have become exhausted by use. Here, like with lactate fermentation, the desired product is the regenerated NAD +. C) reduction of pyruvate to form lactate. In liver cells, the inner mitochondrial membranes are about five times the area of the outer mitochondrial membranes. Course Hero is not sponsored or endorsed by any college or university. NAD is produced in the second step of fermentation when acetaldehyde is converted to ethanol. For glycolysis to continue the NADH must be reoxidized to regenerate NAD +. Answer: 1. During fermentation, an organic electron acceptor (such as pyruvate or acetaldehyde) reacts with NADH to form NAD +, generating products such as carbon dioxide and ethanol (ethanol fermentation) or lactate (lactic acid fermentation) in the process. If the answers is incorrect or not given, you can answer the above question in the comment box. Also NAD + is regenerated in the process, allowing glycolysis to continue to make ATP in anaerobic conditions. When enough oxygen is available, NADH, formed in glycolysis transfers its hydrogen to oxygen via electron transport chain, and changes to NAD for reuse. Which of the following are directly associated with photosystem I? The ATP made during fermentation is generated by which of the following? The second reaction removes an electron from NADH, forming NAD + and producing ethanol from the acetaldehyde, which accepts the electron. B) oxidation of pyruvate to acetyl CoA. However, under anaerobic conditions (as in very active skeletal muscles, in submerged plants, or in lactic acid bacteria, for example), NADH generated by glycolysis cannot be reoxidized by O 2 . B) oxidation of pyruvate to acetyl CoA. The loss of carbon dioxide reduces the molecule by one carbon atom, making acetaldehyde. In alcohol fermentation, NAD⁺ is regenerated from NADH by A) reduction of acetaldehyde to ethanol (ethyl alcohol). Ethanol is excreted, and in most animals, is converted to acetaldehyde and then acetic acid, before finally ending up as acetyl-CoA. Fermentation will replenish NAD+from the NADH + H+produced in glycolysis. Lactic acid fermentation is the mechanism that occurs in the muscle cells. 2. In the second step, acetaldehyde is reduced to ethanol by NADH, which regenerates NAD+.
