Despite this problem, many use oxygen as a terminal electron acceptor for respiration.

In this context, the oxidizing agent is called an 'electron acceptor'.

Generally, electron acceptors and nutrients are the two most critical components of any delivery system.

During respiration, they use oxygen as the terminal electron acceptor.

The reaction centers in this complex are secondary electron acceptors.

When oxygen is not present, a variety of other molecules can serve as electron acceptors.

In aerobic organisms, oxygen is used as the electron acceptor.

The terminal electron acceptor in methanogenesis is not oxygen, but carbon.

As discussed above, acidophiles can have the option to use electron acceptors other than oxygen.

Two electrons need to be passed to an electron acceptor for the process of photosynthesis to proceed.
