What happens to the rate of ATP production if O2 is removed from the environment?

ATP stands for adenosine triphosphate and is the energy source used by cells. The production of ATP is much greater in the presence of oxygen. In the presence of oxygen, 34-38 ATP are produced per glucose molecule. In the absence of oxygen, the net yield of ATP produced is 2 per glucose molecule.
