The idea is that the photon, the particle of light, the sunlight, the quantum of light captured by a chlorophyll molecule, is then delivered to what's called the reaction center, where it can be turned into chemical energy.
Idén var att fotonen, ljuspartikeln, solljuset, ljuskvanten som fångas av klorofyllmolekylen, levereras till ett så kallat  reaktionscenter, där den kan omvandlas till kemisk energi.
