Document Summary

The stages of cellular respiration are glycolysis, transition step, krebs cycle and the electron transport chain. Glycolysis occurs in the cytoplasm and the rest of the steps take place within the mitochondria. Oxygen is not required for glycolysis, but oxygen is required for the rest of the steps. Glycolysis needs one glucose, two nad+ and two h+, as well as 2 adp and two phosphate. The result is 2 pyruvates, 2 nadh and 2 atp. Krebs cycle needs 2 acetyl coa, 2 adp, 2 phosphate, 6 nad+, 6 h+, 2 fad and 4 h+. The result is 4 co2, 6 nadh, 2 atp and 2 fadh2. The electron transport chain needs nadh and fadh2 and yields 34 atp and h2o. A redox is a reduction oxidation reaction in which one substance is reduced, or gains electrons (becomes more negative) and one substance is oxidized, or loses electrons (becomes more positive). The final electron acceptor in cellular respiration is oxygen.
