The efficiency of energy transfer between the two tuning forks depends on their distance from each other and their relative orientation, as well as on their vibrational frequencies, or pitches, Energy transfer in antenna complexes is usually very efficient;

#Unit 6. System Physiology – Plant
  1. The electron transfer is a purely physical phenomenon, energy transfer involves chemical (redox) reaction
  2. Approximately 95 to 99% of the photons absorbed by the antenna pigments have their energy transferred to the reaction centre, where it can be used for photochemistry
  3. The efficiency of energy is measure in terms of the fraction of absorbed photons that engage in photochemistry
  4. Approx. 2 to 10% of the overall energy transfer efficiency per photon, including all loss processes and considering the entire solar spectrum as energy source, is significantly lower
