This is the basis for your need to breathe in oxygen. Oxygen is essential in cellular respiration because it acts as the final electron acceptor in the electron transport chain, allowing the efficient production of ATP. Without oxygen, the electron transport chain halts, and cells must rely on less efficient anaerobic processes.
Oct 31, 2023 · The chemical reactions of lactic acid fermentation are the following: Pyruvic acid + NADH ↔ lactic acid + NAD +. Figure 7.14.1 7.14. 1: Lactic acid fermentation: Lactic acid fermentation is common in muscle cells that have run out of oxygen. The enzyme used in this reaction is lactate dehydrogenase (LDH).
Figure 7.5.2 7.5. 2: Lactic acid fermentation is common in muscle cells that have run out of oxygen. Tremetol, a metabolic poison found in the white snake root plant, prevents the metabolism of lactate. When cows eat this plant, it is concentrated in the milk they produce. Humans who consume the milk become ill.
When cells were deprived of oxygen, researchers noticed a high level of a molecule called succinate. When you add electrons to oxygen at the end of the electron transport chain, it picks up two protons and becomes water. When you add electrons to fumarate, it becomes succinate. “This led us to think that maybe this accumulation of succinate ...
4.11 Summary. The cells of most living things produce ATP from glucose by aerobic cellular respiration, which uses oxygen. Some organisms instead produce ATP from glucose by anaerobic respiration, which does not require oxygen. An important way of making ATP without oxygen is fermentation.

Lactic Acid Fermentation. The fermentation method used by animals and certain bacteria, such as those in yogurt, is lactic acid fermentation (Figure 7.16).This type of fermentation is used routinely in mammalian red blood cells, which do not have mitochondria, and in skeletal muscle that has an insufficient oxygen supply to allow aerobic respiration to continue (that is, in muscles used to the ...
