enzymes catalyze chem. reactions with substrates. Substrates transform into 1 or more products. released from " active site," substrate is then able 2 receive another substrate molecule.
Two substrates bind to the active site of the enzyme. The enzyme catalyzes the reaction (lowers the activation energy needed to complete the reaction), and the result is the final product: two substrates bound together, and an enzyme that can go on to catalyze more reactions.
