A suspension of yeast supplied with glucose as its source of energy was transferred from an aerobic environment to an anaerobic one. What do you think would happen to the rate of glucose utilization and the rate of ethanol production after the transfer?

Question

Quizplus · Accepted Answer

In the absence of oxygen, yeast switches to anaerobic respiration (fermentation), which produces ATP by converting glucose into ethanol and carbon dioxide. Therefore, the rate of glucose utilization and ethanol production would both increase because the yeast needs to generate energy efficiently through fermentation to survive.
