Co-Factors are inorganic ions which can increase the rate of reaction as the binding of the ion can make the enzyme-substrate complex form more easily by affecting the charge distribution or the shape of the ESC. The ion can bind with the enzyme or the substrate.
Eg. Amalyse can only break down starch when chloride ions are present.
Co-Enzymes are small organic molecules that bind to the active site for a short period of time. They are changed during the reaction but recycled back into the reaction.
They are important in the reaction because it won't work without them.
