Fig. 3. Mean rate of lactate uptake for Dipsosaurus dorsalis red iliofibularis (rIF) () and white iliofibularis (wIF) () during 2 min incubations with 5 mmol l^–1 intracellular and 5–100 mmol l^–1 extracellular lactate. The lines are the diffusion-corrected uptake rates for rIF (dashed line) and wIF (solid line). Values are means ± S.E.M., N=4–6 for rIF and N=6–10 for wIF. At some points error bars are smaller than the symbols.
