pheophytin การใช้

For photosystem II, when either of the two chlorophyll " a " molecules at the reaction center absorb energy, an electron is excited and transferred to an electron acceptor molecule, pheophytin, leaving the chlorophyll " a " in an oxidized state.
This is followed by the step "'P680 * ?! pheophytin "', and then on to "'plastoquinone "', which occurs within the reaction center of PS II . High-energy electrons are transferred to plastoquinone before it subsequently picks up two protons to become plastoquinol.
