The maximal p/o ratio for these organisms if nadh is used as an electron source is 2.25 ATP.
Complex II of the electron shipping chain, additionally called succinate reductase, is worried withinside the citric acid cycle. It incorporates the enzyme referred to as succinate dehydrogenase that turned into utilized by the citric acid cycle to convert succinate into fumarate and withinside the manner shape FADH2.
-NADH does now no longer undergo Complex II so its e- shipping is unaffected Succinate can be a substrate to guide the Krebs cycle and ATP technology with the aid of using oxidative phosphorylation whilst mitochondrial characteristic is impaired, because it transfers electrons to the breathing chain downstream complicated I.
