Ethanol exposure limits accessibility to mitochondrial AK. Untreated and ethanol-treated hepatocytes (2 × 106 cells/ml) were incubated with digitonin (8 μM) and centrifuged. AK activity was measured in the cytosol (A) and pellet (B), as described in Materials and methods. In (B) the pellet from low-digitonin treated, ethanol-treated hepatocytes was treated additionally with high digitonin (80 μM). Data are means ± SEM of at least six experiments. *p < 0.05 compared to None. **p < 0.05 compared to ethanol.
