Hexokinase III from Rana catesbeiana

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1978
1. Hexokinase III was partially purified from the liver of the American bullfrong, Rana catesbeiana, using DEAE-cellulose column chromatography. 2. It was inhibited by glucose concentrations above 5 x 10(-5) M (pH 5.9), 10(-4) M (pH 6.7) or 10(-3) M (pH 7.5). 3. There was virtually no inhibition by excess glucose at pH 8.7. 4.

Oxygen uptake in bullfrog tadpoles (Rana catesbeiana)

The Journal of Experimental Zoology, 1998
Weight-specific rates of aquatic oxygen consumption (VO2, microliter O2 g-1 h-1) at 23 degrees C were determined for water-breathing (e.g., forcibly submerged) bullfrog tadpoles as functions of stage of development and O2 tension (PO2). The VO2 at an O2 tension near that of air-saturated water (PO2 approximately 154 mmHg) was independent of stage of ...
