Inhibitors of Oxidative Phosphorylation Several chemicals can block electron transfer in ETS, or transfer of electrons to oxygen. All are strong poisons. Most common in bacteria. Most alternative electron acceptors are inorganic molecules, but some organic molecules can serve. As with aerobic respiration, anaerobic respiration uses ETS, membrane localization, proton gradient, and ATP synthase.
Processes are of great importance both ecologically and industrially.
Process called denitrification . Also called dissimilative nitrate reduction. Reduced waste products are excreted in significant amounts. So organisms respiring anaerobically gain less energy than with oxygen. Requires new terminal oxidase called nitrate reductase .
