An anion exists in higher concentration inside a neuron than outside, the membrane is only permeable to the anion, and the neuron has a negative membrane potential. Which one of the following statements is true? a. Inward movement of the anion would depolarize the neuron (make the inside more positive). b. The equilibrium potential for the anion has a positive value. c. The electrical gradient tends to drive the anion into the neuron. d. The chemical gradient tends to drive the anion into the neuron. e. If the membrane permeability for the anion were to increase further, the neuron would be hyperpolarized (the inside would become more negative).
