How Does Exercise Affect the Rate of Breathing? A derivative of pyruvate, such as acetaldehyde during alcohol fermentation, or pyruvate itself during lactic acid fermentation; oxygen during aerobic respiration. The final electron acceptor in aerobic respiration is oxygen, according to McGraw Hill Education.

In aerobic respiration, the final electron acceptor (i.e., the one having the most positive redox potential) at the end of the ETS is an oxygen molecule (O 2) that becomes reduced to water (H 2 O) by the final ETS carrier. Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O 2).Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain. This electron carrier, cytochrome oxidase, differs between bacterial types and can be used to differentiate closely related bacteria for diagnoses. In aerobic respiration, the final electron acceptor is an oxygen molecule, O 2. in aerobic respiration, the final electron acceptor, ___, combines with hydrogen ions to form water oxygen the rearrangement and oxidation of intermediates in the … Which of the following statements about cellular... What is the Krebs cycle? nitrate. In anaerobic respiration, other electron acceptors are used, such as sulfate. Aerobic respiration is the process by which a cell makes ATP energy by oxidizing glucose molecules in the presence of oxygen gas. Both of these processes occur during cell metabolism. In aerobic respiration, the terminal electron acceptor is oxygen, which combines with two protons and the gained electrons (from the electron transport chain) to form water. Where in the cell does glycolysis occur. Anaerobic exergonic pathways do not require oxygen and include anaerobic respiration and fermentation. Glycolysis citric acid cycle electron transport. A final or terminal electron acceptor is a molecule that accepts electrons right at the end of a chain of electron transfer. In aerobic respiration, the final electron acceptor is. Compared to aerobic respiration, sulfate reduction is a relatively energetically poor process, though it is a vital mechanism for bacteria and archaea living in oxygen-depleted, sulfate-rich environments. Shuttled to an electron transport chain drive the formation of ATP undergoing respiration, other electron are. As animal and plant cells use oxygen as the terminal electron acceptor in aerobic respiration, pyruvate the., or even carbon dioxide sulfate as a by-product during the oxidation of pyruvate, such as sulfate SO42-!
