Detailed explanation-1: -Cellular respiration produces a maximum of 10 NADH and 2 FADH2 per glucose molecule.
Detailed explanation-2: -The net energy output for one glucose molecule from glycolysis through the Krebs cycle is: 4 ATP, 10 NADH + H+, and 2 FADH2.
Detailed explanation-3: -Answer and Explanation: 30 ATP are produced from the 10 NADH that are formed during the citric acid cycle.
Detailed explanation-4: -When electrons from NADH move through the transport chain, about 10 H +start superscript, plus, end superscript ions are pumped from the matrix to the intermembrane space, so each NADH yields about 2.5 ATP.
Detailed explanation-5: -The ten NADH that enter the electron transport originate from each of the earlier processes of respiration: two from glycolysis, two from the transformation of pyruvate into acetyl-CoA, and six from the citric acid cycle. The two FADH2 originate in the citric acid cycle.
