A monophasic proton uptake with a rate constant of about 8 x 10 (3) s-1 and a stoichiometry of 0.8 H+/bo were recorded, using the indicator dye, Cresol red, at pH 8.2.
Comparison of these results with those obtained in an earlier investigation of the bovine cytochrome c oxidase [(1992) Biochemistry 31, 11853-11859], indicates differences between the two oxidases with respect to the role of protons in oxygen reduction and/or the mechanism of proton uptake from the medium.

Structural changes can be correlated to an increase in hepatic lipid and protein contents as well as stimulation of mitochondrial (cytochrome c oxidase), peroxisomal (catalase, allantoinase, uricase), lysosomal (arylsulfatase), and microsomal (esterase) enzymes.
