Document Summary
2 ways to get energy fermentation: macromolecules energy without oxygen. Respiration food (carbs, fats, proteins) + o2 co2 +h2o + energy(atp + heat) Glucose+oxygen carbon dioxide + water + energy. E- movement can releases energy, reaction that involves movement of e- Ex. methane burning : methane is oxidized, oxygen is reduced. Ch4 + o2 co2 + energy +2h2o. Food electron nadh oxygen (slow handoff is controlled electron transport. Glycolysis - food to pyruvate (substrate level phosphorylation) chain atp) Energy investment phase glucose being brought in. Glucose 2 pyruvate 2 acetyl coa 6 nadh 2 fadh2 . Krebs (citric acid cycle) - acetyl coa to co2 (substrate level phosphorylation) Electron transport chain - electrons to o2 (oxidative phosphorylation) inner membrane of the mitochondria. Changes in shape to move protons to the inner membrane space moved against electron gradient. Occurring on the inner membrane of the mitochondria. Chemiosmosis +electron transport chain = oxidative phosphorylation.
