What is the CO2 byproduct in ATP production in the cell?

Explanation:
CO2 is released when fuel molecules are oxidized in the mitochondria as part of cellular respiration. In the Krebs cycle, acetyl-CoA is oxidized to CO2, and this process also generates energy carriers (NADH and FADH2) that feed the electron transport chain. The electron transport chain uses those carriers to drive most of the ATP production through oxidative phosphorylation. So CO2 is a byproduct of the aerobic steps that lead to ATP, not produced by protein synthesis, oxygen transport, or photosynthesis. For glucose metabolism, six CO2 molecules are produced per glucose molecule, reflecting the two acetyl-CoA passes through the cycle.
