-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.
aerobic respiration: glycolysis, Krebs cycle, and electron transport chain anaerobic respiration: glycolysis, fermentation (lactic acid or alcohol)
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.
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
The brain needs a lot of oxygen because it is highly metabolically active, constantly performing complex tasks like thinking, processing information, and regulating bodily functions. Oxygen is essential for generating energy through cellular respiration, which powers the brain's activities and maintains its overall function.
Cardiovascular System
Glycolysis is the only part of cellular respiration that does not require oxygen. It is the process by which glucose is broken down to produce pyruvate and a small amount of ATP. The subsequent steps of cellular respiration, including the Krebs cycle and electron transport chain, require oxygen to fully extract energy from glucose.

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.

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.
Features that are reverse of one another: In photosynthesis, carbon dioxide is converted into glucose, while in cellular respiration, glucose is broken down to produce carbon dioxide. Photosynthesis produces oxygen as a byproduct, whereas cellular respiration consumes oxygen as a reactant. Features that are not reverse: Both pathways involve the use of electron transport chains to generate ATP. Both pathways occur in specialized organelles - photosynthesis occurs in the chloroplasts, while cellular respiration occurs in the mitochondria.
Cell respiration occurs in the mitochondria
