- catalyse metabolic reactions
- globular proteins
- have an active site to bind to enzymes determined by the tertiary structure
Activation energy
Requird to start the react. Enymes reduce the amount of activation energy needed. Reactions occur at a lower temperature therefor the enzymes speed the reaction up.
Enzyme-Substrate Complex
Formed when an enzyme binds to a substrate. When two substrates are held close together by the enzyme they're binded to repulsion is reduced and they can bond more easily. Or in a break down reaction the binding strain the bonds of the substrate breaking it up more easily.
The Induced Fit
As the substrate binds the active site changes shape slightly.
