Respiration by definition refers to oxygen exchange. However cellular metabolism which does not require oxygen is called glycolysis.

Photosynthesis and cellular respirationcellular respiration
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.
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.

The two parts of cellular respiration that require oxygen are the Krebs cycle (citric acid cycle) and the electron transport chain. Oxygen is the final electron acceptor in the electron transport chain, which is essential for the production of ATP.

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.
