D.
Chargaff's rule
Answer: Option A
Solution
Answer: Option A
Solution:
A sudden change from anaerobic to an aerobic process produces Pasteur Effect.The Pasteur effect describes how available oxygen inhibits ethanol fermentation, driving yeast to switch toward aerobic respiration for increased generation of the energy carrier adenosine triphosphate (ATP).
The effect was described by Louis Pasteur in 1857 in experiments showing that aeration of yeasted broth causes cell growth to increase while the fermentation rate decreases, based on lowered ethanol production.
