Enzymes speed up the rate of chemical reactions by lowering the energy of activation (the amount of energy needed to begin a reaction).nzymes speed up the rate of chemical reactions by lowering the energy of activation (the amount of energy needed to begin a reaction).
Enzymes are large molecules that speed up the chemical reactions inside cells. Each type of enzyme does on specific job. Enzymes are a type of protein, and like all proteins, they are made from long chains of different amino acids.ach enzyme will only speed up one reaction as the shape of the enzyme molecule needs to match the shape of the molecule it reacts with (the substrate molecule). The part of the enzyme molecule that matches the substrate is called the active site. Your web browser does not have JavaScript switched on at the moment.
