Guided Notes
Key concepts students will learn:
- •
Enzymes are mostly proteins that speed up reactions by binding to substrates at the enzyme's active site.
- •
Enzymes are considered catalysts because they are not used up in a reaction and can be used over and over.
- •
If the pH or temperature is not ideal, an enzyme can become denatured, which means it loses its shape and can no longer function.
