ENERGENTICS OF PHOTOSYNTHESIS (6 pts): One of the common sugars that plants produce is sucrose (12-carbon sugar). The chemical bonds in sucrose contain 5643 kJ of energy. We know from Web Topic 8.4 that the Calvin-Benson Cycle uses about 3648 kJ of energy for every six carbons fixed.
What proportion of the energy fixed is converted to energy in the bonds of sugar? This gives us an idea of how efficient the Calvin-Benson Cycle is (2 pts).
Nine moles of photons are used to fix 2 NADPH and 3 ATP. How many moles of photons are required to supply the necessary products to supply enough of these molecules to allow for the production on sucrose (3 pts)?
