What are the most important characteristics of an enzyme?

Enzymes speed up reactions by bringing reactants together and reducing the activation energy required to start the reaction (enzymatic reaction). Enzymes are specific: they have a specific shape, therefore only a certain substrate will fit its active site.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
