The photochemical quantum efficiency (quantum yield) is nearly 100%, the energy conversion efficiency is only 27%, and the overall efficiency of conversion of solar

energy is only a few percent the solar energy storage efficiency is a measure of how much of the energy in the entire solar spectrum is converted to usable form, if it

can be measure in terms of C3 and C4 plant?

#Section 2: General Biology
  1. The energy in the entire solar spectrum is converted to usable form- approx. 2%  for C3 and 8% for C4
  2. The overall energy conversion efficiency into biomass, including all loss processes and considering the entire solar spectrum as energy source, is significantly lower still—approximately 4.3% for C3 plants and 6% for C4 plants
  3. The overall energy conversion efficiency into biomass, including all loss processes and considering the entire solar spectrum as energy source, is significantly higher still—approximately 4% for C3 plants and 6% for C4 plants
  4. Energy transfer efficiency in antenna complexes approximately 99% for C3 and C4 plants
