Glycolysis, the first stage of aerobic respiration, occurs in a cell's cytoplasm. The second stage (acetyl-CoA formation and the Krebs cycle) and the third stage (electron transfer phosphorylation) occur inside a cell's mitochondria. They occur at the inner mitochondrial membrane, which is highly folded.
Therefore, most of the reactions of aerobic cellular respiration occur inside the mitochondria of a cell.
Anaerobic respiration involves chemical reactions in cytoplasm without O2. This is in contrast with aerobic respiration which involves reactions in mitochondria with O2 needed.

It is TRUE that AEROBIC respiration requires oxygen to occur. It is FALSE that ANAEROBIC respiration requires oxygen to occur. It is FALSE that cells are DEPENDENT on AEROBIC respiration.
Generally it will occur in the presence of oxygen, which is aerobic respiration, but there are other times where no oxygen will be present and cellular respiration will occur anaerobically (fermentation). Aerobic respiration is more beneficial because you produce more ATP than anaerobically.
Aerobic cellular respiration requires oxygen. Therefore which ever process that requires Oxygen to make it occur is NOT a stage of aerobic cellular respiration.
Cellular RespirationSource: Holt Biology by Johnson Raven* Aerobic cellular respiration. Anaerobic cellular respiration yields a net gain of 2 ATP molecules for each glucose molecule broken down. Aerobic respiration yields a variable number, but always more than ten times as many ATP molecules.
No, it occurs during aerobic cellular respiration.

Cellular respiration (aka, aerobic respiration) takes place in the mitochondria (singular is mitochondrion).
Aerobic cellular respiration occurs in the mitochondria of the cell. This process involves breaking down glucose to produce ATP, which is the main energy source for the cell.
