Cells use anaerobic respiration when there is no oxygen available.

Glucose is a supplier of energy to the cells. Cells use the glucose as well as fats for fuel.
Energy and oxygen. The process is called photosynthesis.
No cell produces oxygen; oxygen is made in the hearts of stars. Plant cells responsible for photosynthesis, liberateoxygen from carbon dioxide molecules. Plants use the carbon to made carbohydrates (with the hydrogen from water) and the oxygen is the waste product.
cells use the oxygen to release chemical energy.

cellular respiration
For the most part, oxygen is used to help cells generate energy from carbon sources. Some cells can use oxygen to generate toxins which are used to kill pathogens.
Oxygen is needed for respiration. This is how all our cells release energy. All the body cells and white blood cells therefore need oxygen. Red blood cells don't use oxygen, they undergo anaerobic respiration, but they transport the oxygen needed by other cells.
