Fig. 2. Glycerol, dihydroxyacetone phosphate (DHAP), glycerol 3-phosphate (G3P), inorganic phosphate (P_i), pyruvate, lactate and glucose levels in liver of rainbow smelt subjected to a controlled decrease in temperature. Values are means ± s.e.m., N=6 at each point with the exception of –0.5°C where N=12. Different letters indicate significant differences between values. Transition time and plasma glycerol levels for this experiment are presented in Fig. 1B.
