Photosynthesis is largely responsible for maintaining and producing oxygen content of the earth's atmosphere. The source of oxygen evolved in photosynthesis:Photolysis of water is the main source of oxygen released during photosynthesis. During the light reactions, an electron is stripped from a water molecule freeing the oxygen and hydrogen atoms. Green pigments found in chloroplast, that absorb light during photosynthesis. What are the light reactions? The overall reaction is something like this: 6 CO2 + 6 H20 + energy <-> C6H12O6 + 6 O2. Explain the energy flow and conversion of photosynthesis. Where do the electrons that drive photosystem II ultimately come from? Thus we can say that oxygen liberated during photosynthesis comes from water. Cornelius van Niel experimentally proved for the first time that the oxygen liberated during photosynthesis comes from water and not from carbon dioxide. Remember, the electrons lost from the reaction center in photosystem II must be replaced. Light ''excites'' electrons in pigment molecules, and light provides the energy to split water molecules, providing more electrons as well as hydrogen ions. This is the light independent portion of the photosynthetic process. 2. The gas exchange that occurs when stomata are open facilitates photosynthesis. The light-harvesting complex (or antenna complex) is an array of protein and chlorophyll molecules embedded in the thylakoid membrane of plants, which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem.
