1.In photosynthesis ferredoxin is involved in electron transfer between photosystem I and the final electron acceptor, NADP.
光合作用中,铁硫蛋白与光合系统Ⅰ和最终受体NADP间的传有。
2.plants also derive additional ATP through cyclic photophosphorylation, in which some electrons are shunted back through the electron transport chain between photosystems Ⅱ and Ⅰ.
