If O₂and N₂ are present in equal amounts in an environment, both will have an equal chance of serving as an electron acceptor during respiration (i.e., organisms do not have a preference as to which molecule is reduced).

Question

Quizplus · Accepted Answer

Organisms often show a preference for electron acceptors based on their redox potential, availability, and the energy yield from their reduction. Therefore, they may prefer one molecule over another as an electron acceptor during respiration.
