Final answer:
Aerobic pathways require oxygen as the terminal electron acceptor and are part of cellular respiration.
Step-by-step explanation:
The metabolic pathways that require oxygen are referred to as aerobic. Aerobic pathways involve the use of oxygen as the terminal electron acceptor in the process of cellular respiration. This process produces a large amount of ATP, the cell's energy currency. An example of an aerobic pathway is aerobic cellular respiration.
