Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following processes creates the most ATP during aerobic cellular respiration?
A
glycolysis
B
fermentation
C
electron transport chain
D
Kreb’s cycle
Explanation: 

Detailed explanation-1: -Electron Transport System generates 32 or 34 ATP molecules and is the cell’s main source of energy. Thus, the electron transport system produces the most ATP in cellular respiration.

Detailed explanation-2: -Oxidative phosphorylation, which involves the electron transport chain that produces maximum ATP. It takes one NADH molecule via Channel 1 to produce 2.5 ATP and one FADH2 molecule via channel 2 to produce 1.5 ATP, for a total of 34 ATP.

Detailed explanation-3: -The majority of ATP synthesis occurs in cellular respiration within the mitochondrial matrix: generating approximately thirty-two ATP molecules per molecule of glucose that is oxidized.

Detailed explanation-4: -The electron transport chain produces 28 ATP molecules. Since 4 ATP molecules were produced earlier in the cellular respiration process, this means the whole process produces 32 ATP molecules. The electron transport chain is formed by four protein complexes arranged in descending order of energy.
