Mr. Johnson is giving a lesson on enzymes in his freshman biology class. Mr. Johnson displays six beakers with either a chemical
substrate or chemical enzyme in them. He tells the class that each of the substrates will spontaneously degrade over a set period of time. He asks the class to identify what would happen if he were able to apply the correct enzyme to the correct substrate. Which of the following is the best answer to give Mr. Johnson? A The reaction would stop immediately. B The reaction would be maintained. C The reaction rate would increase. D The reaction rate would decrease.
Enzymes are organic catalysts produced to control the chemical reactions. enzymes are specific in the reactions they catalyze. An enzyme will only catalyze one specific reaction. When appropriate enzymes and substrates are added, the rate of reaction increases steadily. The substrate fits in the active site of the enzyme. This forms an enzyme-substrate complex. The enzyme speeds up product formation. The products formed separate from the enzyme so that other substrate molecules can fit into the active site.
