Photosynthesis and quantum randomness

Click For Summary
SUMMARY

The discussion centers on the relationship between quantum randomness and the process of photosynthesis, specifically regarding how electrons behave during energy transport. It is established that electrons in photosynthesis can travel all possible paths simultaneously before collapsing at the reaction center, which raises questions about the predictability of their location post-collapse. The conversation references two significant studies that explore quantum coherence in photosynthesis, highlighting ongoing research in this area.

PREREQUISITES
  • Understanding of quantum mechanics principles, particularly quantum randomness.
  • Familiarity with photosynthesis and its biochemical processes.
  • Knowledge of quantum coherence and its implications in energy transfer.
  • Ability to interpret scientific literature and research studies.
NEXT STEPS
  • Review the study "Quantum Coherence in Photosynthesis for Efficient Solar Energy Conversion".
  • Explore the implications of quantum mechanics in biological systems.
  • Investigate the mechanisms of energy transport in photosynthesis.
  • Learn about the role of quantum coherence in enhancing solar energy efficiency.
USEFUL FOR

Researchers, biophysicists, and students interested in the intersection of quantum mechanics and biological processes, particularly those studying photosynthesis and energy conversion mechanisms.

Some studies suggest that during photosynthesis, electrons travel all possible paths simultaneously, and then always collapse at the reaction center.

My question is, doesn't that contradict quantum randomness? Shouldn't the location of the electron after the collapse be predictably random?

Welcome to the PF. :smile:

Can you post links to the studies you are referring to? That would probably help to get you better answers to your question. Thanks! :smile:

Thanks! Here are two (as far as I know this topic is now heavily researched):

https://www.researchgate.net/publication/270879144_Quantum_Coherence_in_Photosynthesis_for_Efficient_Solar_Energy_Conversion

I'm a layman, I guess I can't tell whether or not there's a mechanism involved here that can nearly perfectly "steer" the energy transport. Without such a mechanism it would seem to me to contradict quantum randomness.
