Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many ATP are produced during the electron transport chain?
A
32
B
2
C
36
D
100
Explanation: 

Detailed explanation-1: -The electron transport cycle generates around 30–32 ATP molecules, according to a recent study. This NADH consequently produces one to two ATP.

Detailed explanation-2: -The electron transport chain is the final step of cellular respiration where 34 ATP molecules are produced.

Detailed explanation-3: -The electron transport chain is located on the inner membrane of the mitochondria. The electron transport cycle yields around 30-32 ATP molecules, according to current studies.

Detailed explanation-4: -Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).

Detailed explanation-5: -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. Therefore, a total of up to 36 molecules of ATP can be made from just one molecule of glucose in the process of cellular respiration.
