Which of the following statements regarding the equilibrium potential (Eion) of an ion is correct? The equilibrium potential for potassium is less negative than the resting membrane potential. The electrical force that acts upon potassium attracts potassium to the interstitium. The chemical force that acts upon sodium drives sodium out of the cell. At an ion’s equilibrium potential, the electrochemical force is zero.

Which of the following is the correct statement regarding ion channels? Physical deformation of the membrane cannot open ion channels Ligand-gating means that an ion binds to the channel, which stimulates its opening.
