ELECTRON MICROSCOPIC EVIDENCE FOR THE LOCATION AND AMOUNT OF ION ACCUMULATION BY SPINACH CHLOROPLASTS

Electron Microscopic Evidence for the Location and Amount of Ion Accumulation by Spinach Chloroplasts

Light-Dependent Ion Translocation in Spinach Chloroplasts.

The absorption of light by chloroplasts is the first step for several energy-requiring systems such as ATP synthesis and CO, fixation. Recently. it has been found that light can alter the structure and volume of the chloroplast (7, 15, 17, 26). Therefore the question was raised whether light could affect ion movements in isolated chloroplasts under conditions where structural changes occur. Thi...

Electron nuclear double resonance evidence supporting a monomeric nature for P700 in spinach chloroplasts.

Proton electron nuclear double resonance (ENDOR) spectra of P700(+) in spinach chloroplasts and in photosystem I particles have been obtained and compared with the corresponding ENDOR spectrum of monomeric chlorophyl a(+) (Chla(+)) cation radical. The hyperfine couplings for P700(+) can be interpreted in terms of those expected for a monomer Chla(+) radical. The reduction in alpha-carbon spin d...
