Here are some things that can affect enzyme activity:
1. Temperature - The temperature can affect the reaction rate. The higher the temperature, the the reaction will occur. However, at some point, the temperature will become so high that the enzyme will and stop working.
2. pH - An extreme pH (high or low) will typically slow the reaction or even the reaction altogether.
3. Concentration - A concentration of substrate or enzyme can increase the reaction rate.
4. Inhibitors - Inhibitors are molecules that are specially made to stop the activity of enzymes. They may just slow down the reaction or stop it altogether. Some inhibitors bond with the enzyme causing it to change shape and not work correctly. The opposite of an inhibitor is an which can help to speed up the reaction.
Match the enzyme terms to their definitions.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Denaturation | arrow_right_alt | Location on the enzyme where the substrate binds |
Inhibitor | arrow_right_alt | Protein that acts as a biological catalyst |
Active site | arrow_right_alt | Substance that speeds up a chemical reaction |
Enzyme | arrow_right_alt | Change in enzyme structure, usually caused by extreme heat or pH |
Catalyst | arrow_right_alt | Substance that slows down or stops enzyme activity |

What reference does she make toward the enzymes?
Most enzymes are a
The site where the binding occurs on the enzyme is called

Enzymes are not necessary for chemical reactions, but they can ______________ chemical reactions
Enzymes are known as _________ and they can be used over and over and over again
Match the correct enzyme to the macromolecule it breaks down.
