Key concepts
3 concepts
- 1
Enzymes are mostly proteins that speed up reactions by binding to substrates at the enzyme's active site.
- 2
Enzymes are considered catalysts because they are not used up in a reaction and can be used over and over.
- 3
If the pH or temperature is not ideal, an enzyme can become denatured, which means it loses its shape and can no longer function.
