RESUMO
Physical activity of respiratory and olfactory cilia of animals and humans in the context of L.A. Blumenfeld concept, according to which protein molecules are "machines that perform chemical transformation" and create "a meaningful order", has been investigated and analyzed.

Unbiased criteria (Lissajous figures, entropy, and harmonic spectra) have been developed to estimate the transition from an unordered to an ordered motor activity of olfactory cilia, which occurs by the action of odorants on flagellata.

The motility of olfactory cilia of frog (Rana temporaria) was studied by vital video microscopy under an exposure to odorants: pentanol, camphor, cineole, vanillin (first group), ammonia, and hydrogen sulfide (second group) as well as inhibitors of cell respiration (rotenone and malonate). It was shown that olfactory cilia have both a dynein-tubulin and an actin-myosin molecular motility system. The first molecular motility system provides unordered movements and the second, ordered movements. Motility ordering occurs under the exposure to odorants. The effects of odorants of different groups on mitochondrial respiratory chain activity and olfactory cilia motility are different.
