When an organism such as a yeast lives by fermentation, it converts the pyruvate from glycolysis into a different compound, such as alcohol. Why doesn't it secrete the pyruvate directly? Group of answer choices The conversion yields one NADH per pyruvate molecule. A buildup of pyruvate in the surrounding environment would be too toxic. The conversion is needed to regenerate the molecules needed for glycolysis. The conversion yields 32 ATP per pyruvate molecule.

The conversion is needed to regenerate the molecules needed for glycolysis

Explanation:

Fermentation is a metabolic process by which microorganisms generate ATP by the anaerobic (without oxygen) degradation of organic nutrients. Fermentation allows to microorganisms convert carbohydrates into alcohol or acid. During glycolysis, two NAD+ molecules are reduced and glucose molecules are split into two pyruvate molecules, thereby producing two NADH molecules and two ATP molecules. During fermentation, pyruvate molecules are metabolized to different compounds because the energy stored in the pyruvate molecules is unavailable to the cell. In fermentation, NADH from glycolysis is oxidized back to NAD+ by being used to reduce pyruvate or a pyruvate derivative.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.
