Type: MCQ-conceptual-Hard-Class 11
Which of the following statements about fermentation is correct?
A
Fermentation results in the complete oxidation of glucose to CO2 and H2O.
B
NADH is oxidized to NAD+ very slowly during fermentation.
C
Fermentation occurs only in aerobic conditions.
D
Alcoholic fermentation is catalyzed by pyruvic acid decarboxylase and lactate dehydrogenase.
Correct Answer
Option B
Detailed Explanation
In fermentation, NADH is oxidized to NAD+ relatively slowly, while aerobic respiration allows for a more vigorous oxidation. Fermentation does not completely oxidize glucose, nor does it occur in aerobic conditions, and lactate dehydrogenase is not involved in alcoholic fermentation.
