-Oxidative phosphorylation: oxygen is the final electron acceptor in the electron transport chain, it also breaks apart and combines with 4 hydrogen atoms to form 2 water molecules.
-The Citric Acid Cycle occurs only when oxygen is present but it doesn't use oxygen directly.
Kreb's (citric Acid) Cycle and Electron Transport System
If oxygen is available, the process is an aerobic respiration, in opposite to anaerobic respiration, which does not need oxygen. More info can be found on http://en.wikipedia.org.wiki/Cellular_respiration
Oxygen is required for cellular respiration in all cells. During photosynthesis oxygen gas is produced, this is used to produce glucose; oxygen is also then used during anaerobic respiration to break down the glucose to ATP. Oxygen for normal cellular respiration in other parts of the plant is supplied in solution via the root system.
Your cells need the oxygen to function. That's why it's called "cellular respiration."and you blood needs to be oxygenated so it can carry the O2 (oxygen) to other parts of the body.
Well, one could look at as all the parts of an engine having a specialized task to perform for the engine to function. In much the same way, cell respiration has a 3 step process that it uses to perform specialized tasks and breakdown of enzymes and glucose that it uses to function. Furthermore, certain parts of an engine require certain things- just like the Krebs cycle and the electron transport system both require oxygen.
1 I believe Cellular respiration only occurs in plant cells.Cellular respiration occurs in both plant and animal cells. In animal cells, the organelle for cellular respiration is the mitochondrion.
Respiration by definition refers to oxygen exchange. However cellular metabolism which does not require oxygen is called glycolysis.
In human lungs. Because lungs is the only part where cellular respiration takes. This is the only part that helps in take in oxygen, utilize it to other parts and then give off Carbon Dioxide.

The electron transport chain is the aerobic step of cellular respiration. Oxygen is the last electron acceptor in the electron transport chain. The last step in aerobic respiration is the bonding of 2 electrons, 2 protons, and oxygen to form water. The water leaves the electron transport chain, freeing up a place for another oxygen molecule so that the electron transport chain does not stop.
