Fig. 7. Activity of pyruvate kinase (PK) from the mantle and posterior adductor
muscle (PAM) of M. barbatus during acclimation to different water
temperatures. Activity (µmol min–1 g–1
wet mass) was determined at 2 mmol l–1
(Vmax; open circles) and 0.05 mmol l–1 of
phosphoenolpyruvate (PEP; Vo; filled circles). Values are
means ± s.e.m.; N=10 preparations from different animals.
