Activities of aerobic and anaerobic enzymes in the adductor muscle of N. subnodosus scallops exposed to control conditions (22 °C) and acute hyperthermia challenge (30 °C) in the spring (black) and summer (white). (A) Hexokinase activity (HK, U g−1). (B) Pyruvate kinase activity (PK, U g−1). (C) Citrate synthase activity (CS, U g−1). (D) Cytochrome c oxidase activity (CCO, U g−1). (E) Octopine dehydrogenase activity (ODH, U g−1). (F) Arginine kinase activity (AK, U g−1). See the legend of Fig. 3 for the relevant statistical data.
