Enzymes enzymes - substances that carry out most of the catalysis in living organisms RNA may also carry out some catalysis substrates - molecules undergoing a reaction temporarily stabilizes an association between substrates, lowering activation energy carbonic anhydrase - increases production of carbonic acid from 200/hr to 600,000/sec active sites - pockets/clefts on the enzyme where substrates bind to form enzyme- substrate complex substrate must fit perfectly in an active site for catalysis to work; proteins adjust shapes into an induced fit between it and the substrate amino acid side groups of enzymes stress/distort certain bonds, weakening them enzymes that take many forms - some function as parts of cell membranes/organelles multienzyme complex - associations of several enzymes catalyzing different steps in a reaction sequence o doesn't require that products of 1 reaction dissociate to move on to the next enzyme o no unwanted side reactions o all reactions within the complex can be controlled as a unit
