Abstract
The effect of such flavonoid as quercetin and its oxidized from on electron transfer was studied in subchloroplast preparations of the Photosystem II (PS(2) and Photosystem I (PS(1)). Quercetin and its oxidized form are shown to inhibit the electron transfer in the PS(2) acceptor and donor sites, respectively. They also function as an electron donor or and electron acceptor in PS(1)), respectively
摘要
在光系统II（PS(2)）和光系统I（PS(1)）的亚叶绿体制剂中，研究了槲皮素及其氧化形式等类黄酮对电子转移的影响。结果表明，槲皮素及其氧化形式分别抑制PS(2)受体和供体位点的电子转移。它们在PS(1)中还分别作为电子供体或电子受体发挥作用。
