A form of chemolithotrophy in which the nitrogenous compounds donate electrons to an ETC is known as Anaerobic respiration in which the electron acceptor is an oxidized nitrogenous compound that is reduced to nitrogen gas is known as Some bacteria carry out anaerobic ammonia oxidation (anammox) using a membrane-bound organelle called the In this organelle, ammonia is coupled with the reduction of nitrite, generating nitrogen and water.

Those bacteria which use anaerobic respiration use the same organic molecules as those bacteria using aerobic respiration to make energy. HOWEVER, instead of using ___________ as the final electron acceptor in the electron transport chain, they use inorganic compounds such as sulfate. On the other hand, the denitrifying bacteria can use the compound ________________________.

What happens if oxygen is not present as the final acceptor of glucose's electrons? This situation is called anaerobic respiration. In anaerobic respiration, oxygen is not the final electron acceptor. In the table below, you will notice that many species of bacteria have evolved to use anaerobic respiration; therefore, they can live in areas that are inhospitable to species that require oxygen. In class, you will learn about yet another way to metabolize glucose, called fermentation, which is different than either aerobic or anaerobic respiration. Oxygen is an efficient final electron acceptor because it has a relatively high affinity for electrons (0.82 V), measured as a redox potential value (V). Based on the redox potential values in the table, which molecule offers the next best option as the final electron acceptor of glucose's electrons? a. Iron b. Nitrate c. Sulfate
