Answer:
200 ATP molecules
Explanation:
Yeast is a fungus that undergoes fermentation instead of cellular respiration when there is an absence of oxygen. In the fermentation process undergone by yeast, which produces an alcohol as product (alcohol fermentation), two (2) ATP molecules are produced as net ATP.
However, if a yeast cell undergoes fermentation and uses 100 molecules of glucose, the yeast cell will generate a net ATP of 2 × 100 molecules = 200 molecules.
