Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which process in aerobic cellular respiration makes the most ATP?
A
Krebs Cycle
B
Glycolysis
C
Fermentation
D
ETC (Electron Transport Chain)
Explanation: 

Detailed explanation-1: -The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS). The inner mitochondrial membrane holds the ATPase enzyme and the complexes for ETS.

Detailed explanation-2: -How much ATP is produced in all three stages combined? Glycolysis produces 2 ATP molecules, and the Krebs cycle produces 2 more. Electron transport from the molecules of NADH and FADH2 made from glycolysis, the transformation of pyruvate, and the Krebs cycle creates as many as 32 more ATP molecules.

Detailed explanation-3: -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-4: -During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
