Fig. 6. Temperature dependence of of lactate dehydrogenase (LDH) in crude homogenates prepared from muscle (circles) and liver (triangles) of cod (Gadus morhua) acclimated to different temperatures. Two-phase linear regression analysis of the temperature dependence of reveals that at temperatures below 16±1°C (shaded area) the is almost independent of temperature (the slope of the curve is 0.003 mmol l^–1 deg.). Values are means ± S.E.M. (N=21 for 4°C and N=15 for 12°C). ns, not significant. The dotted line indicates the upper border of data accepted for regression analysis.
