Detailed explanation-1: –The transfer of an electron to molecular oxygen combines with H+ to form water is marked as an end product in the oxidative phosphorylation pathway. So, the correct answer is, ‘ATP+H2O.

Detailed explanation-2: -Oxidative phosphorylation produces 24–28 ATP molecules from the Kreb’s cycle from one molecule of glucose converted into pyruvate. Two theoretical approaches applied to the oxidative phosphorylation are metabolic control analysis and nonequilibrium thermodynamics.

Detailed explanation-3: -Beyond those four, the remaining ATP all come from oxidative phosphorylation. Based on a lot of experimental work, it appears that four H +start superscript, plus, end superscript ions must flow back into the matrix through ATP synthase to power the synthesis of one ATP molecule.

Detailed explanation-4: -The by-products of the breakdown of ATP are adenosine diphosphate (ADP), which is the remaining adenosine and two (di) phosphate groups, and one single phosphate (Pi) that is ‘on its own’.

Detailed explanation-5: -The products of oxidative phosphorylation are ATP, NAD+, and FAD+. The NADH and FADH produced during glycolysis and the Krebs cycle are used to reduce electron carriers in the electron transport chain before finally being passed on to oxygen.
