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.
系统发育影响了三种硬骨鱼（即印度野鲮、胡子鲶和斑鳢）各组织中己糖激酶的分布，这三种硬骨鱼在生长速率、摄食习惯和获取氧气的能力等多个参数上存在显著差异。在对己糖激酶进行研究的器官中，肝脏右叶前部区域的活性高于后部区域，其次是左叶的前部和后部区域。肾组织中部区域的活性高于前部或后部区域。在肌肉中，尾部区域的活性高于头部或胸部区域。然而，在鳃中，左鳃的酶浓度高于右鳃。结合生理状态对观察到的差异进行了讨论。
