RESUMO

The influence of zinc on the energetic metabolism of green algae was investigated. It has been found that the functioning of succinate dehydrogenase was stimulated at the concentration of the ions of zinc in the medium of 1.0 and 2.0 mg/L. At the same time, the functioning of cytochrome-c-oxidase was stimulated at all the studied concentrations of the ions of zinc. It is likely that the stimulating effect of the ions of Zn²⁺ in relation to the enzymes of algae energetic metabolism was conditioned by mobilization of the protective resources of algae cells, and also by a direct influence of the metal on individual enzyme systems.
