WebbHerbicides such as paraquat and diquat interact with the electron transfer components associated with Photosystem I. Under normal circumstances, the electrons pumped to high energy by P-700 are transferred to ferredoxin, which in turn transfers electrons to NADP +, forming NADPH. Webb6 mars 2024 · PS II performs this duty best with light at a wavelength of 680 nm and it readily loses an electron to excitation when this occurs, leaving PS II with a positive charge. This electron must be replaced. The ultimate replacement source of electrons is water, but water must lose four electrons and PS II can only accept one at a time. …
