Which statement is true for anaerobic fermentation?

a. ATP is generated by consuming oxygen

b. NAD+ is regenerated

c. None of the choices listed

d. Pyruvate is oxidized to Lactate

e. More than one of these choices

Solution

Answer: b. NAD+ regenerated.

Option a is not true as during anaerobic fermentation, organism lack oxygen so they cannot consume oxygen.

Option b is true since during anaerobic fermentation NAD+ is regenerated (from NADH) which is required for glycolysis.

Option c is not true as b is true.

Option d is not true as during anaerobic fermentation in vigourously contracting muscles, erythrocytes and in some cells, pyruvate is reduced (not oxidized) with the help of reducing agent NADH to form lactate.

Option e is not true as only one choice is right.
