1.In photosynthesis ferredoxin is involved in electron transfer between photosystem I and the final electron acceptor, NADP.
在光作用中,铁硫蛋白与光统Ⅰ和最终电子受NADP间的电子传递有关。
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.
