I. Introduction
Photosynthesis is the process that plants use to convert light energy into chemical energy. The reactants of photosynthesis include carbon dioxide (CO2), water (H2O), and light, and the products that are produced come out to be sugar in form of glucose (C6H12O6) and oxygen (O2). The reaction equation is as follows: 6CO2 + 6H20 + light -> C6H12O6 + 6O2. The variable being tested in this experiment is the affect of light on the rate of photosynthesis. Photosynthesis occurs in the chloroplast; the absorption of light takes place in the thylakoid membrane of the chloroplast and the sugar formation takes place in the stroma, which is the fluid within the chloroplast that surrounds the thylakoid. Photosynthesis occurs because this is the process that plants use to make its own fuel and energy. Photosynthesis occurs in plants to convert light to chemical energy to be used by other organism and also to release oxygen for humans in cellular respiration (Stegenga 24). The Hill reaction consists of transferring high-energy electron that comes from water to produce oxygen. It shows that the electrons are boosted to a higher energy level when light is absorbed and are moved around electron-acceptor molecules that are alternatively being reduced and oxidized. In this process NADP+ is reduced to NADPH, which is the source for the synthesis reaction (Stegenga 27). Reduction potential is the willingness of a molecule to be reduced or accept an electron. It is measured in volts and the more positive the number, the higher chance of the molecule to accept an electron and be reduced (Redox Potentials). This relates to our
