Is antimycin a a specific inhibitor of the slow rise of the electrochromic absorbance change in intact chloroplasts?

The inhibitory effect of antimycin A on the slow rise of the flash-induced electrochromic absorbance change was reinvestigated in intact chloroplasts isolated from pea leaves. It is show that in the absence of nigericin and +K at low repetition rates (<0.5 s −1) of the excitation flashes not only...

Summary:The inhibitory effect of antimycin A on the slow rise of the flash-induced electrochromic absorbance change was reinvestigated in intact chloroplasts isolated from pea leaves. It is show that in the absence of nigericin and +K at low repetition rates (<0.5 s −1) of the excitation flashes not only the slow (∼ 10 ms) rise but also the initial (⪡1 ms) rise generated by photosystem 1 is inhibited by antimycin A.
