Question

The conversion of one mole of glucose 6 phosphate to tow moles of ethanol by the fermentative pathway of anoxia tolerant goldfish is accompanied by a net yield of:

Answer 1

In the anoxia-tolerant goldfish, the conversion of one mole of glucose 6-phosphate to two moles of ethanol through fermentation yields a net of two ATP molecules.

Step-by-step explanation:

The conversion of one mole of glucose 6-phosphate to two moles of ethanol during fermentation in an anoxia-tolerant goldfish results in a net yield of energetic molecules. In the fermentation process, two molecules of NAD+ are reduced to two NADH, while glucose is converted to pyruvate, which then leads to the production of ethanol. From the provided information, we can deduce that there is a net yield of two ATP molecules from glycolysis, taking into account that the Entner-Doudoroff Pathway nets one ATP during this process. The subsequent conversion of pyruvate to ethanol allows for the regeneration of NAD+ from NADH, but does not yield additional ATP.
