Question

For bacteria to continue growing rapidly when they shift from an aerobic environment to an anaerobic environment, they must

Answer 1

The answer to this question would be: e. increase the rate of the glycolytic reactions.

Lack of oxygen limits the possible chemical reaction that can be done to produce energy. In the anaerobic environment, fermentation of glucose would be the source of energy for bacteria. The net amount of ATP can't be increased, so you need to increase the rate instead.
