Study Notes
Enzymes
- Enzymes are biological molecules, typically proteins, that speed up chemical reactions
- Enzymes are highly specific, meaning each enzyme only catalyzes one specific reaction or a small group of closely related reactions
Active Site
- The active site is the region on an enzyme where the substrate binds
- The active site is shaped in such a way that it allows only specific substrates to bind, ensuring the enzyme's specificity
Role in Chemical Reactions
- Enzymes act as biological catalysts, increasing the rates of chemical reactions
- Enzymes do not alter the equilibrium of a reaction, but rather allow it to reach equilibrium faster
- Enzymes can operate under mild conditions, such as temperatures and pH ranges, found in living organisms
Naming of Enzymes
- The common ending for the names of enzymes is "-ase"
Lock & Key Model
- The Lock & Key model describes the binding of a substrate to an enzyme's active site
- According to this model, the shape of the active site is complementary to the shape of the substrate, ensuring specific binding
