[Cooperative processes in mitochondria: registration by dyanmic phase microscopy].

The spectra of phase fluctuations in mitochondria were measured by the method of dynamic phase microscopy. Contrasting components were revealed whose intensity markedly changed at distances of 100-300 nm. Similar frequency components were observed in the spectra of ATP-stimulated fluctuations in liposomes with the incorporated ATPase. The values of the frequency and intensity of contrasting components in spectra of liposomes, mitochondria, and cells are presented. The possibility of determining the position of active enzyme complexes from their characteristic frequencies is discussed.
