Many catabolic biochemical processes, such as glycolysis, the citric acid cycle, and beta oxidation, produce the reduced coenzyme NADH. This coenzyme contains electrons that have a high transfer potential; in other words, they will release a large amount of energy upon oxidation. However, the cell does not release this energy all at once, as this would be an uncontrollable reaction. Inst… WebOct 11, 2024 · Oxidative phosphorylation, through its highly efficient production of ATP and unique regulatory design, is able to set and maintain metabolic homeostasis over wide ranges ATP utilization.
