Guided Notes
Key concepts students will learn:
- •
Enzymes have a specifically shaped area called the active site where substrates can bind.
- •
Enzymes are considered catalysts because they can be used over and over again and are not used up in the reaction.
- •
If an enzyme's environment changes outside of its ideal pH or temperature range, the enzyme can become denatured, meaning it can no longer bind to its substrate.
