Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many ATP molecules are created by fermentation?
A
0
B
2
C
12
D
36
Explanation: 

Detailed explanation-1: -Thus a total of 2 ATPs are generated from the fermentation of a glucose molecule.

Detailed explanation-2: -Fermentation is the process of producing ATP in the absence of oxygen, through glycolysis alone. Recall that glycolysis breaks a glucose molecule into two pyruvate molecules, producing a net gain of two ATP and two NADH molecules.

Detailed explanation-3: -Net ATP production when one molecule of glucose is fermented to alcohol or lactic acid: When glucose ferments, there is a net gain of two ATP molecules in the glycolysis process. Both lactic acid and alcoholic fermentation proceed in the same way.

Detailed explanation-4: -Fermenters make very little ATP-only two ATP molecules per glucose molecule-during glycolysis. Yes, fermentation produces ATP.

Detailed explanation-5: -During formation of lactic acid by anaerobic respiration 2 molecules of ATP are produced.
