Abstract— Photosynthesis and
respiration participates in energy
production by plants undo different light conditions. It looks quite
important to provide a balanced regulation of these processes. It was
show in presented study that succinate dehydrogenase activity drops
down in intact leaves undo intensive light/ There is no direct
influence of light to purified enzyme. It was found that low
concentrations of ATP (2 - 5 mkM) activated succinate dehydrogenase
(SDH) but concentration more than 30 mkM inhibit it. Presented data
supports idea that enzyme regulation is provided by oscillations of
cell metabolites concentrations.
