Abstract: Regulation of oxygen consumption of oxidative muscle is exerted by various factors such as ADP, phosphorylation potential, phosphocreatine/creatine ratio, intracellular Ca2+, nitric oxide and oxygen [1-4]. Permeabilized muscle fibers and isolated cardiomyocytes display pronounced limitation for ADP transport when compared with isolated mitochondria [5]. Whereas the outer mitochondrial membrane is the proposed mechanism for transport limitation for the charged molecule ADP [6-7], biological membranes do not constitute any barrier for oxygen diffusion. Nevertheless, oxygen affinity is significantly reduced in respiration of permeabilized muscle fibers [8]. In the present study we addressed the problem of oxygen limited respiration by comparing the oxygen kinetics in permeabilized muscle fibers, collagenasetreated permeabilized muscle fibers and isolated mitochondria.
