Water-soluble barium salts are toxic to humans. Potassium sulfate and magnesium sulfate are used as emergency treatments for barium chloride poisoning. These work by reacting with the barium chloride to form barium sulfate. Barium sulfate is less dangerous due to its insolubility in water.
Best Answer: Photosynthesis: 12 H2O + 6 CO2 -> 6 O2 + C6H12O6 + 6 H2O. 12 water molecules and 6 carbon dioxide molecules are the reactants. 6 oxygen molecules, 1 glucose molecule, and 6 water molecules are the products. Light dependent reaction happens at the thylakoid membrane, made up of lipid bilayers, which is conveniently located in the chloroplast -> Light-independent reaction (the Calvin-Benson Cycle) happens in the stroma -> creation of glucose molecule.
You are here. Light Dependant Reactions. The first reactions of photosynthesis require light energy, and are called light dependant reactions. The aim is to produce ATP from ADP and inorganic P and harvest hydrogen so that carbon dioxide can be reduced to form a carbohydrate in the second series of reactions. The production of ATP using light is called photophosphorylation.
