How enzymes work
There are three ways of thinking about the job of enzymes. They all describe the same process, but in
different ways.
Reaction Mechanism
In any chemical reaction a substrate is converted into a product. In an enzyme catalysed reaction, the
substrate will first bind to active site of the enzyme to form what is known as an enzymesubstrate complex,
then substrate is then converted into the product while attached to their active site and then the product is
released.…read more

Here's a taster:

Enzymes speed up a reaction by: Holding substrate molecules at the correct angle, difficult in collisions. The
polar groups on active site are arranged to change arrangement of charge helping a reaction to occur.
Active site acts as an acid or base, donating or accepting protons from substrate.…read more
