AP Biology – Enzymes ACTUAL Exam
Questions and CORRECT Answers
chemical reaction - CORRECT ANSWER - A process that changes one set of chemicals into
another set of chemicals.
reactants - CORRECT ANSWER - compounds that enter into a chemical reaction
product - CORRECT ANSWER - compounds produced by a chemical reaction.
enzyme - CORRECT ANSWER - biological catalysts usually globular that speed up the rate
of chemical reactions
coenzyme - CORRECT ANSWER - A non protein organic molecule serving to modify the
active site of an enzyme before the reaction is allowed to occur. Most vitamins function
important metabolic reactions in this role.
Competitive inhibition - CORRECT ANSWER - substance that resembles the normal
substrate competes with the substrate for the active site
Noncompetitive inhibitor - CORRECT ANSWER - a chemical that binds to an enzyme but
not in the active site. This chemical will change the shape of the enzyme (reversible)
substrate - CORRECT ANSWER - the substance an enzyme catalyzes, changes.
active site - CORRECT ANSWER - the location on the enzyme where the substrate binds and
goes through a chemical reaction.
exothermic reaction - CORRECT ANSWER - a chemical reaction where energy is given off,
so that the products have less energy than the reactants.
