Question

Which of the following is CORRECT for the Pasteur Effect?

(a) Utilization of glucose for fermentation

(b) Increased glucose consumption by yeast in anaerobic condition

(c) Fermentation favors aerobic condition more than anaerobic

(d) Increased consumption of glucose by yeast in aerobic condition

This question was posed to me by my college director while I was bunking the class.

The query is from Respiration in section Bioenergetics and Metabolism of Life Sciences

Answer 1

Correct choice is (b) Increased glucose consumption by yeast in anaerobic condition

For explanation: Lois Pasteur observed that yeast does not show good ethanol production or glucose consumption when they are exposed to the aerobic condition. This shows that yeast consumes more glucose anaerobically than aerobically.
