Document Summary

Oxidation simply refers to the loss of electrons to an electron acceptor, so it does not need to involve oxygen: glycolysis oxidizes glucose to 2 molecules of pyruvate. Neither oxygen or the etc is involved. Types of fermentation: fermentation is a way of harvesting chemical energy w/o using either oxygen or any etc, fermentation consists of glycolysis plus reactions that regenerate nad+ by transferring electrons form. The nad+ can then be reused to oxidize sugar by glycolysis, which nets two. What are the two steps in alcohol fermentation? molecules of atp by substrate-level phosphorylation. Glycolysis followed by the reduction of pyruvate to ethyl alcohol. Lactic acid fermentation: pyruvate is reduced directly by nadh to form lactate as an end product with no release of. Co2: human muscle cells make atp by lactic acid fermentation when oxygen is scarce. Muscle cells switch from aerobic respiration to fermentation.
