Lec09 mechanisms of enzyme action continued: http://higheredbcs. wiley. com/legacy/college/voet/0470129301/guided_exp/guided_exploratio n_11/michaelis_menten. html a. click link for a review of michaelis menten kinetics mechanisms of enzyme action. 4. specific role of particular amino acids in the active sites of an enzyme. 2. transfer of electrons from one species to another: oil rig, oxidation is loss of electrons b. reduction is gain of electrons. 4. redox a. reactions always occur together: one substrate is oxidized, one is reduced, oxidizing agent a. causes oxidation b. takes electrons from substrate being oxidized c. the agent itself becomes reduced. 6. reducing agent a. causes reduction b. the agent itself becomes oxidized: oxidation, e. g. a. i. removal of hydrogen a. i. 1. most common a. ii. addition of oxygen a. iii. removal of electrons. 1. catalysts (enzymes) a. lower activation energies: participate in reactions by stabilizing transition states c. accelerate reactions by lowering the overall activation energy energy diagram for a reaction with intermediates.
