Abstract

Respiration is a universal process and a fundamental basis of life of any living cell. Respiration produces energy (adenosine triphosphate [ATP]), reducing equivalents (NAD(P)H) and carbon skeletons to sustain synthesis de novo and maintain integrity and functional activity of cellular structures, tissues, and organs of the whole organism. Respiration is an indicator of functional stability of living objects. Respiration acts as the mechanism accelerating evolution. It is known that DNA oxidation by reactive oxygen species (ROS) formed during respiration is the major tool of natural mutagenesis (Skulachev 1999). Therefore, the respiration has captured the interest of scientists for more than two centuries.
