61 views6 pages

Document Summary

General aspects of energy production: oxidation-reduction reactions, mechanism of atp (adenosine triphosphate) generation. Fad flavine adenine dinucleotide: oxidation reaction dehydrogenation, most released energy stored within atp. Mechanisms of phosphorylation of atp generation: substrate level phosphorylation atp is generated by the direct transfer of a high energy phosphate group to adp, oxidative phosphorylation energy released by a series of redox reactions generates. Atp utilizing the electron transport chain: photophosphorylation generates atp through a series of sunlight driven reactions utilizing an electron transport chain. Apoenzyme simple enzyme protein + non-protein (cofactors) cofactors: metallic cofactors (iron, magnesium, zinc, or copper ions) or enzyme activators, co-enzyme (organic molecule) Holoenzyme (active enzyme) apoenzyme + cofactors catalyst reusable specific tertiary structure active or catalytic site lowers the energy of activation. E + s ______> (es) _______> e + p. Factors influencing enzyme activity: temperature, ph, concentration of substrate, concentration of enzyme, inhibitors. Temperature low temperature inhibits catalysis high temperature denaturation ph destabilization of tertiary structure.
