oxidation of NADH by nitrate produces 5 ATP, by H2S is 2 ATP, by O2 is 3 ATP. Why oxidation of NADH by nitrate could produce more ATP, whereas by H2S is less.
An intact Krebs cycle is frequent in microbes that use anaerobic respiration, allowing them to utilise the energy stored in NADH and FADH2 molecules.
Anaerobic respirers utilise modified Electron Transport Chain carriers encoded in their genomes, which include different complexes for electron transport to their ultimate electron acceptors. Because these electron transfer systems generate smaller electrochemical gradients, anaerobic respiration produces less ATP.
