Each enzyme has only one specific reaction it can perform. . 2. How many different reactions can a single enzyme perform?. Yes, the same enzyme molecule can be used over and over. protein. !. Enzymes are . Biological . catalysts . that . increase. . the rate of metabolic reactions.. Since enzymes speed up chemical reaction rates, what are they called?. Catalyst- . A substance . Part 1. . Chapter 3. Learning outcomes. You should be able to:. explain how enzymes work. describe and explain the factors that affect. enzyme activity. use V. max. and K. m. to compare the affinity of different enzymes for their substrates.
