Paper instructions: 750- to 1,050-word paper, including the equations requested below, describing the important steps of photosynthesis. Provide the equation for photosynthesis. Explain where each reactant comes from and how the plant gets it. Then, explain the importance of each product for life on earth. What is an absorption spectra? Explain why a green leaf looks green. Is it the same reason a red leaf looks red? Explain your answer. What is the main energy-carrying molecule in the process of photosynthesis? How does it carry energy? Where does it carry energy? Provide the reactants and products of the light reactions. Describe how the light reactions work. Use a diagram or picture. Provide the reactants and products of the Calvin cycle. Describe the three phases of these reactions. Use a diagram or picture. Provide the equation for photosynthesis again. For each reactant, explain how it is used within the light reactions or Calvin cycle. For each product, describe how it is generated by either the light reactions or by the Calvin cycle.
The leftover oxygen atoms from splitting water form waste oxygen gas, the Hydrogen ions are used to make ATP, and the electrons are passed down the "electron transport chain".
There are actually two electron pumping stations, called photosystems, in the light reaction, which is more efficient than one.
The ATP energy produced in the light reaction is actually captured light energy which will end up STORED in a glucose molecule.
The dark reactions are often called "The Calvin Cycle" after the botanist Melvin Calvin who discovered the chemical reactions that occur in the dark reaction.
The hydrogen ions are then used to produce ATP by a process called Chemiosmosis.
At the end of the electron transport chain, the electrons are picked up, along with hydrogen ions, by a special molecule called NADP which carries them to the dark reaction.
Remember, the purpose of the light reaction was to produce ATP and H atoms for the dark reaction.
The products of the dark reaction are glucose and more RuBP, mostly RuBP.
Six "turns" of the calvin cycle (dark reaction) are needed to produce a single molecule of glucose.
By 1796, after further research, Ingenhousz was able to write the first equation for photosynthesis, which was:
Light is not directly usable in photosynthesis.
