A Polymerase B Hydroserae C Isomerase D Enzymate

A Co-factor B Co-enzyme C Holoenzyme D App enzyme

A Cause chemical reactions that would not otherwise take place B Change the rate of chemical reactions C Change the direction of reactions D Raise the activation energy

A Enzyme 2 would be partially denatured. B Substance x would increase in concentration. C Substance y would no longer be formed. D The initial reactant would no longer be metabolized.

A Apoenzymes and prosthetic group B Proenzymes and prosthetic group C Coenzymes and prosthetic group D Proenzymes and apoenzymes

A Amylase B Transferase C Catalase D Lipases

A An increase in the substrate concentration (at constant enzyme concentration) leads to proportional increase in the rate of reaction. B Most enzymes operating in the human body work best at a temperature of 37c C An enzyme is generally inactivated rapidly by exposure to ultraviolet light. D Competitive inhibitors reduce the productivity of enzymes by blocking the substrate from entering active site.
