Louis Pasteur observed that when oxygen is introduced to cells consuming glucose at a high rate in an anaerobic environment, fermentation ceases and the rate of glucose consumption decreases. This phenomenon is called the Pasteur effect. The basis of this effect is the shift from fermentation to oxidative phosphorylation to regenerate NAD*. Additionally, the cells also synthesize ATP through oxidative phosphorylation. In respiration-deficient yeast mutants that lack cytochrome oxidase, the Pasteur effect is not seen. Select the reasons why the...
