2.  Enzyme: A protein that is capable of speeding up specific reactions by lowering the required activation energy.  The agents that carry out most of the catalysis in living organisms are called enzymes.  An enzyme alters the activation energy of a reaction.  The unique three dimensional shape of an enzyme enables it to stabilize a temporary association between substrates- the molecules that will undergo the reaction.

3.  The enzyme itself is not changed or consumed in the reaction.  There are thousands of enzymes and different types of cells have different types of enzymes.  Active sites of enzymes conform to fit the shape of substrates.  Most enzymes are globular proteins with one or more pockets or clefts, called active sites.

4.  Substrates bind to the enzyme at these active sites, forming an enzyme-substrate complex- the complex formed when an enzyme binds with its substrate.  Enzymes occur in many forms.

6.  Enzymes can occur in many forms  An Enzyme’s function depends on its ability to maintain its three dimensional shape  This could be affected by temperature and ph.  Optimum temperature is the rate of an enzyme catalyzed reaction  Optimum pH ranges from 6-8

7.  A substance that binds to an enzyme and decreases its activity is called an inhibitor.  Enzyme inhibition occurs in two ways:  Competitive inhibitors compete with the substrate for the same active site, occupying the active site and thus preventing substrates from binding.  Noncompetitive inhibitors bind to the enzyme In a location other than the active site, changing the shape of the enzyme and making it unable to bind to the substrate.
