Document Summary
Glucose is broken down yielding energy breakdown is catabolic synthesis or build up is anabolic. C6h1206 + 602 -> 6co2 + 6h2o + energy glucose + oxygen = carbon + water + energy used for body maintenance and voluntary activity average human needs 2200 calories a day. Molecular basics energy obtained by transferring electrons from organic molecules to oxygen usually hydrogens movement of h+ represents electron movement involves series of steps coupling endergonic and exergonic reactions. Oxidation: lose electrons or h+ losing potential energy. Reductions: gain electrons or h+ gaining potential energy. Hydrogen carriers (nad+) shuttle electrons paired endergonic- exergonic relations are know as redox (reduction- oxidation) reactions breakdown of glucose involved series of these reactions at each breakdown portion oxidized and nad+ reduced to nadh. Energy released when electrons fall from hydrogen carrier to oxygen small amounts of energy released to make atp.
