The overall goal of photosynthesis to enrich CO2 with electrons to create chemical potential energy. These electrons are taken from H20 in the first step of the light reactions. Demonstrate your comprehensive knowledge on this subject by explaining how the electrons are taken from H2O and added to CO2. Use your knowledge of biochemistry and redox chemistry to explain which molecules are oxidized and reduced at each step of the process.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
