FERMENTATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When humans exercise, which of the following is not a source of ATP?
A
lactic acid fermentation
B
ATP stored in muscles
C
cellular respiration
D
alcoholic fermentation
Explanation: 

Detailed explanation-1: -Lactic acid fermentation is carried out by certain bacteria, including the bacteria in yogurt. It is also carried out by your muscle cells when you work them hard and fast. This is how the muscles of the sprinter in Figure 5.10. 1get energy for their short-duration but intense activity.

Detailed explanation-2: -These are used primarily in the production of ethanol fuel. Human use of alcoholic fermentation depends on the chemical energy remaining in pyruvate after glycolysis. Transforming pyruvate does not add ATP to that produced in glycolysis, and for anaerobic organisms, this is the end of the ATP-producing line.

Detailed explanation-3: -Thus a total of 2 ATPs are generated from the fermentation of a glucose molecule.
