Unformatted text preview: 1 Chapter 9: Cellular Respiration Harvesting Chemical Energy Important Point: Bioenergetics Oxidation and Reduction Oxidation is the Loss of Electrons E.g., something that is oxidized in the course of a chemical reaction with Oxygen has had electrons stolen by Oxygen Reduction is the Gain of Elections E.g., a gain of electrons results in a decrease (reduction) in electrical charge (since electrons carry a negative charge) Metal ores are Reduced to metals (via the addition of electrons)metals found in ores are in an oxidized form relative to metals found as metals Hydrocarbon Oxidation to CO 2 Note relative position of e-v Exergonic! Hydrocarbon Oxidation to CO 2 Recall that as carbon is increasingly oxidized, fewer and fewer hydrogens are bound to the carbon 2 Dehydrogenases Nicotinamide Adenine Dinucleotide Nicotinamide Adenine Dinucleotide NAD! Big Energy Powers Engines Rapid release of energy associated with electrons Big machines are required to harness big energy Movement Toward Equilibrium in Steps Little machines are better at doing things in little steps 2 Types of ATP Generation Oxidative vs. substrate-level phosphorylation are are concepts whose distinction may not make sense to you until weve covered the entire chapter...
