Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many ATP are produced in aerobic respiration?
A
2
B
28
C
4
D
38
Explanation: 

Detailed explanation-1: -In aerobic respiration, the full oxidation of one glucose molecule can theoretically yield 38 ATP molecules.

Detailed explanation-2: -So, in aerobic respiration, a total of 38 molecules of ATP are created, with 2 ATP molecules formed outside the mitochondria. Electron transfer from glycolysis’ NADH and FADH2 molecules, pyruvate transformation, and the Krebs cycle generates up to 32 additional ATP molecules.

Detailed explanation-3: -There are 38 ATP molecules produced in aerobic respiration all together, and 2 ATPs are formed outside the mitochondria. Note: For the use of glucose energy, fermentation is less efficient: only 2 ATP per glucose is produced, as opposed to 38 ATP per glucose nominally produced by aerobic respiration.

Detailed explanation-4: -Final answer: Out of 38 ATP molecules produced per glucose, 32 ATP molecules are formed from NADH/ FADH2 in the respiratory chain.

Detailed explanation-5: –During the complete process of aerobic respiration the total number of ATP molecules produced are 38. This process occurs through the breakdown of one molecule of glucose.
