The Use of Oxygen as the Terminal Electron Acceptor Is

Question

The use of oxygen as the terminal electron acceptor is called
A) aerobic respiration.
B) anaerobic respiration.
C) fermentation.
D) oxygenic photosynthesis.
E) carbon dioxide fixation.

Accepted Answer

The use of oxygen as the terminal electron acceptor is a characteristic of aerobic respiration, where oxygen is used to produce energy by breaking down organic molecules. This process is different from anaerobic respiration and fermentation, where other molecules are used as electron acceptors. Oxygenic photosynthesis is not related to the use of oxygen as an acceptor, but rather the production of oxygen as a by-product. Carbon dioxide fixation is a process where carbon dioxide is transformed into organic molecules during photosynthesis, and is not related to the acceptor of electrons.
