Glycolysis occurs in the cytosol, but the Krebs cycle and electron transport chain occur inside the mitochondria. Electron carriers such as NADH produced during glycolysis and the Krebs cycle pass their electrons to the electron transport chain, which results in synthesis of a lot of ATP.
The air that we breathe is mostly made up of nitrogen (78%). 21% is oxygen which is needed for animals and humans in respiration and 0.03% is carbon dioxide which is needed for plants to make energy in a process called photosynthesis. The bit that is left is made up of rare gases like helium and argon and methane.
