Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In aerobic conditions, one glucose molecule can produce
A
2 ATP
B
26-30 ATP
C
32-36 ATP
D
38-40 ATP
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: -When a single glucose molecule is broken down in aerobic cellular respiration, about 30-32 ATP molecules are produced within the cell. The number depends on the type of cell that we are considering.

Detailed explanation-3: -Hence, during the complete oxidation of one molecule of glucose, 38 molecules of ATP are produced.

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: -The ATP yield for aerobic respiration ranges from 36-38 ATP while the ATP yield for anaerobic respiration is only 2 ATP per molecule of glucose.
