Question

which type of cellular respiration requires oxygen? aerobic photoaerobic all cell respiration requires oxygen anaerobic

Explanation:

Cellular respiration is a process that cells use to convert nutrients into energy. Aerobic respiration specifically requires oxygen ($O_2$) as the final electron acceptor in the electron - transport chain. Anaerobic respiration does not require oxygen (it uses other molecules like sulfate or nitrate as electron acceptors). Photoaerobic is not a standard type of cellular respiration classification in basic biology (it may be a misnomer or a very specialized term not relevant here). And it's incorrect to say all cell respiration requires oxygen because anaerobic respiration exists.

Answer:

aerobic
