Abstract
The kinetics of reduction of P-680, oxidized by a flash, have been measured with chloroplasts treated with Tris, hydroxylamine or cholate, with PS-II particles from Phormidium (Tris-treated) and with subchloroplast particles prepared with digitonin or Triton. In all cases the electron transfer from D1 to P-680+ has similar rates, influenced similarly by pH and D1 has a one-electron capacity.
摘要
用经Tris、羟胺或胆酸盐处理的叶绿体、来自席藻属（经Tris处理）的PS-II颗粒以及用洋地黄皂苷或 Triton制备的亚叶绿体颗粒，测定了被闪光氧化的P-680的还原动力学。在所有情况下，从D1到P-680+的电子转移速率相似，受pH的影响也相似，并且D1具有单电子容量。
