14. Is carbon dioxide involved in the light-dependent reaction?
15. Refer to Model 2.a.Write a chemical reaction that summarizes all of the chemical reactions in the light-dependentreactions of photosynthesis starting with two water molecules.
b.In the photosynthesis reaction in Model 1, twelve water molecules are shown as reactants, butsix water molecules are shown as products. Are any of the twelve water molecules products ofthe light-dependent reactions?c.Calculate the total number of oxygen, NADPH, and ATP molecules that are produced whentwelve water molecules complete the light-dependent reactions.16. Where do the ATP and NADPH produced during the light-dependent reactions go when theprocess is complete?
