1. Enzymes
Unit: Ecology

2. Enzymes are…
Proteins
-made of amino acids
-shape is important!

3. Enzymes are…
2. Catalysts -speed up chemical reactions

4. Enzymes are…
3. Specific -shape “fits” with a specific substrate

5. Enzymes are…
4. Reusable -after a chemical reaction, they can be used again

6. Enzymes can be… Denatured
Which means they do not work anymore because their shape is changed.
Caused by change in:
Temperature pH

7. Product- what you end with, what the substrate turns into (ex
Product- what you end with, what the substrate turns into (ex. Water and oxygen)
Substrate- what an enzyme works on (ex. Hydrogen peroxide)
Active site- where the enzyme and substrate fit together
Enzyme- provides a place for the chemical reaction and therefore lowers the activation energy (Ex. Catalase)
Enzyme-Substrate Complex
*Enzyme can be reused!!
Because it does not change
