Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many ATP are produced in fermentation?
A
0
B
 30
C
2
D
too many to count
Explanation: 

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

Detailed explanation-2: -Without oxygen, some human cells must use fermentation to produce ATP, and this process produces only two molecules of ATP per molecule of glucose.

Detailed explanation-3: -Fermentation involves the step of glycolysis in respiration, but it does not go through the Kreb’s cycle or the Electron Transport Chain. Therefore there are only 2 net ATP generated, not the net of 32 that come from cellular respiration.

Detailed explanation-4: -Fermentation is less efficient at using the energy from glucose: only 2 ATP are produced per glucose, compared to the 38 ATP per glucose nominally produced by aerobic respiration.
