A final or terminal electron acceptor is a molecule that accepts electrons right at the end of a chain of electron transfer. [12] during these redox reactions, NAD+ is reduced,which then oxidizes an electron acceptor in the electron transport chain. This mechanism is very characteristic in its location since it is located in the inner membrane of the mitochondria, that is why it will decide to indicate that option as the correct one. View solution. Oxygen is used as an electron acceptor within the electron transport chain of aerobic respiration to generate adenosine triphosphate, or ATP. Cellular respiration begins when electrons are transferred from NADH and FADH 2 —made in glycolysis, the transition reaction, and the Krebs cycle—through a series of chemical reactions to a final inorganic electron acceptor (either oxygen in aerobic respiration or non-oxygen inorganic molecules in anaerobic respiration).
