12 questions

1. What type of molecule are enzymes?
2. True or false? Enzymes can affect the rate of a reaction.
3. Enzymes ___ the amount of activation energy needed for a reaction to take place.
4. What region on an enzyme does the substrate bind to?
5. What can be said about the shape of the active site and the substrate shape?
6. Put the steps in order to show how an enzyme works.
7. True or false? The concentration of substrate will affect the rate of reaction.
8. At high temperatures the shape of the enzyme's active site can change, and it no longer fits the substrate. We say the enzyme has become ...
9. Match the labels to what is happening.
