In any chemical reaction a substrate is converted into a product. In an enzyme catalysed reaction, the
substrate will first bind to active site…

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.
