Fig. 4. Effects of acclimation temperature and cadmium exposure on cellular energy budgets of isolated gill (A) and hepatopancreas (B) cells of C. virginica. Data for control oysters and for those exposed for 40 days to 50 µg l^–1 Cd are shown (N=6–12). Proportions of the total oxygen consumption in isolated cells due to non-mitochondrial respiration (non-mito), mitochondrial proton leak (proton leak), cytosolic protein synthesis (protein synthesis) and the remaining ATP turnover (MATP) are given.
