Resting Membrane Potential A variety of unusual invertebrates, including giant clams, mussels, and polychaete worms, live on the fringes of deep-sea hydrothermal vents, where the temperature is 60 C. (a) The adductor muscle of a giant clam has a resting membrane potential of -95 mV. Given the intracellular and extracellular ionic compositions shown below, would you have predicted this membrane potential? Why or why not? Ion Nat K+ CI Ca+ Concentration (mm) Intracellular 50 400 21 0.4 Extracellular 440 20 560 10 (b) Assume that the adductor muscle membrane is permeable to only one of the ions listed above. Which ion could determine the Vm?
