Researchers discover quantum switch for regulating photosynthesis

https://phys.org/news/2023-09-quantum-photosynthesis.html

"Light-harvesting complex II pigment molecules switches between dissipating harmful excess light energy as heat through nonphotochemical quenching, and transferring absorbed light to reaction center with almost a unit efficiency under low light... accelerating transition increase photosynthetic efficiency, for example soybean yields, up to 33%... slight change at distance 5.6 Å allow reversible switching enables rapid response changes in light intensity, efficient photosynthesis and balanced photoprotection"
