Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the net gain of ATP at the end of cell respiration?
A
32
B
34
C
36
D
38
Explanation: 

Detailed explanation-1: -The citric acid cycle produces 36 ATP molecules. So, in aerobic respiration, a total of 38 molecules of ATP are created, with 2 ATP molecules formed outside the mitochondria.

Detailed explanation-2: -Reason: There is net gain of 18 ATP molecules during aerobic respiration of one molecule of glucose.

Detailed explanation-3: -In aerobic respiration, one glucose molecule results in a net ATP gain of 38 ATP.

Detailed explanation-4: -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.

Detailed explanation-5: -During citric acid cycle, 36 ATP molecules are produced. So, all together there are 38 molecules of ATP produced in aerobic respiration and 2 ATP are formed outside the mitochondria.
