Fig. 2. Oxygen consumption rates of Sipunculus nudus isolated body wall
musculature measured at different values of extracellular (A) and
intracellular (B) pH during normocapnic or hypercapnic incubation.
*Oxygen consumption rate significantly different from the
respective control value at pHe 7.9. Values are means ± S.D.,
N=5-6.
