The complex chemicals are carbohydrates. The chemical reaction is shown by the equation. Light CO² + H²O C6 H12 O6 + O² Chlorophyll The two reactants are CO² and H²O. The two products are C6 H12 O6 and O². The process is driven by light energy. The light energy is trapped my chlorophyll I have already investigated the nature of chlorophyll using chromatography and found chlorophyll is a complex pigment. Temperature, concentration and the surface area of the reactions affect the chemical reaction of photosynthesis. Enzymes are also important in biological reactions. The reaction CO² + H²O C6 H12 O6 + O² can be tracked by measuring how quickly the reactants are used up or how quickly the products are made. The reactants are...
