Differential distribution of hexokinase in vital organs of three teleost fishes.
The phylogeny has influenced the distribution of hexokinase in various tissues of three teleosts, viz., Labeo rohita, Clarias batrachus and Channa punctatus, which differ significantly in a number of parameters like growth rate, feeding habits and ability to get oxygen. Among the organs investigated for hexokinase, the anterior region of the right lobe of the liver showed higher activity than the posterior region, followed by the anterior and posterior regions of the left lobe. The middle region of the renal tissue showed higher activity than the anterior or posterior region. In the muscle the caudal region showed maximum activity compared to the cephalic or thoracic regions. However, in g ills the enzyme concentration is higher in the left gill than in the right one. The observed variations are discussed in relation to the physiological status.
