Aerobic cellular respiration is the process by which cells use oxygen to help them convert glucose into energy. This type of respiration occurs in three steps: glycosis; the Krebs cycle; and electron transport phosphorylation. Oxygen is not needed for glycosis but is required for the rest of the chemical reactions to take place.


ELECTRON TRANSPORT PHOSPHORYLATION :-)

NADH and FADH2 carry electrons to specialized cell membranes,
where they are harvested to create ATP. Once the electrons are used, they become depleted and must be removed from the body. Oxygen is essential for this task. Used electrons bind with oxygen; these molecules eventually bind with hydrogen to form water.
