Chloroplasts only absorb certain wavelengths in the electromagnetic spectrum‚ the blue followed by the red are the two main wavelengths absorbed (Melis‚ et al.‚ 1987). The experiment was designed to investigate which wavelengths would result in the highest rate of photosynthesis. Chlorophyll a

speed up the rate of reaction without itself being used up in the process. Enzymes provide an alternate reaction pathway by lowering the activation energy needed for a reaction to occur. For two molecules to react they must collide with each other‚ however‚ they have to collide with sufficient energy. Sufficient energy means that between them they have enough energy to overcome the energy barrier to reaction. This is called the activation energy. Even though enzymes can alter the rate of reaction
