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.
