Enzymes
Guided Notes
3 key concepts
- 1
Enzymes are chemicals that speed up a reaction, but are not consumed in the reaction.
- 2
An enzyme's active site is where the substrate binds, allowing a chemical tug that lowers activation energy.
- 3
Competitive inhibition is when a chemical blocks the active site, while allosteric inhibition changes the enzyme's shape.
