WebThe minimum quantum requirement for photosynthesis under optimal conditions is about nine. Thus, the energy used is 9 × 50, or 450 kcal per mole of oxygen evolved. Therefore, the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117 kcal, divided by 450—that is, 117/450, or 26 percent. WebTherefore, one photon can be absorbed by an atom and typically results in an electron being excited to a higher energy orbit. It is not possible to absorb half of a photon if you only need half as much energy. Photons occur in integral numbers. The amount of energy that a photon has can be calculated from Planck’s law. E = h ν = h c / λ WebAnswer (1 of 3): To fix one CO2 molecule, it is needed, at best, 8 photons!
