Question

In alcoholic fermentation, will increasing the number of yeast cells, while holding sugar concentration constant, increase or decrease the rate of ATP production?

Answer 1

Yes, yeast will also naturally multiply during the fermentation process, by increasing the initial colony it will ferment faster, right up to the point the alcohol level gets high enough and kills them all.

Answer 2

The rate of ATP production would initally increase because there would be more yeast creating ATP, but then it would level off and begin to decrease as the amount of sugar available ran out. So the answer is kind of both.
