Explain why synthesis of ATP by ATP synthase does not occur in absence of oxygen?

Synthesis of ATP by ATP synthase does not occurs in the absence of oxygen because oxygen is responsible for the transportation of electrons to the cell from electron transport molecules. This electron is used for the production of ATP. If oxygen is not present during ATP production, electrons will not formed in the system. That's why oxygen is very necessary for ATP production.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
