1. The concentration of an enzyme within a cell is extremely low realtive to other material present, yet functions effectively in its metabolic rate. How can enzyme function and never seem to run out?
2. A chemist found that a reaction did not take place under any set of conditions. If the chemists added a catalyst, would the reaction then occur? Explain your answer?
3. For a given enzyme-catalyzed reaction, on a molar basis, substrate concentration increases from two to four times the enzyme concentration (double). Would the rate of the reaction also double? Explain your answer?
