Consider a species of alien whose neurons that work differently from those of humans. Specifically, the ion concentrations inside and outside the cell membrane are: sodium (150 mM in, 15mM out), chloride (120 mM in, 12 mM out), fluoride (15 mM in, 150 mM out), calcium 0.1 mM in, 5 mM out). At rest, the major leak channel is selectively permeable to flouride. The neuronal membrane also contains voltage-gated channels (which open only in response to membrane depolarization) that are selectively permeable to either sodium or chloride, and the presynaptic terminal contains voltage-gated calcium channels that open only in response to depolarization. The signal for neurotransmitter release is calcium. From the choices below, what would be the effects of the following treatments on a neuron from this alien species? (Do not assume the existence of any channels other than those noted). A. Depolarization of the membrane B. Hyperpolarization of the membrane C. Little immediate effect on membrane potential, but depolarization is more difficult. D. Little effect on membrane potential, but harder to evoke neurotransmitter release E. Little effect on membrane properties or neurotransmitter release 27. ____a____ Opening voltage-gated chloride channels 28. ____b____ Opening voltage-gated sodium channels 29. ____b____ Blocking fluoride leak channels
