Is it easier or harder to make atp with oxygen

easier

Explanation:

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. ATP is formed in the presence of oxygen in the process known as aerobic cellular respiration.
