What Type of Metabolic Pathway Requires Oxygen

Question

What type of metabolic pathway requires oxygen?
A) aerobic
B) anaerobic
C) photosynthetic
D) fermentative

Accepted Answer

Aerobic metabolic pathways require oxygen as a final electron acceptor in the electron transport chain to produce ATP. Anaerobic pathways do not require oxygen and can use alternative electron acceptors. Photosynthetic pathways use light energy to create ATP and organic molecules, while fermentative pathways do not require oxygen but also do not produce ATP as efficiently as aerobic pathways.
