Q4.6. If calcium ions, each of which has a charge of +2 (Ca2*), moved OUT OF a neuron, and no other ions were moving, what would be TRUE? The area outside the neuron would be become more negatively charged. The concentration of Ca2* inside the cell would increase. The neuron would become more negative. The neuron would become more positive.
Q5.6. If calcium ions, each of which has a charge of +2 (Ca²+), moved INTO a neuron, and no other ions were moving, what would be TRUE? The area outside the neuron would be become more positively charged. The concentration of Ca²+ inside the cell would decrease. The neuron would become more negative. The neuron would become more positive. Submit

Q5.8. In a neuron with a Vm of 0, there is a high concentration of K* inside of the cell and a low concentration outside. Which statement below is TRUE? If K+ channels were open and the electrical forces were absent, diffusion would result in a net movement of K* out of the cell. If K+ channels were closed, Na* would flow into the neuron. If K+ channels were open and the effect of diffusion was absent, the electrical forces would move K+ out of the cell. The membrane potential would be at the K* equilibrium potential, because concentrations of K* are not balanced. Submit

Q5.3. After the rising phase, which ion channel is responsible for action potential returning to its resting Vm, and why? Na+ channels, because positive Na* ions are at higher concentration outside the axon than inside, and so they enter the axon and raise V m Na* channels, because positive Na* ions are at higher concentration inside the axon than outside, and so they leave the axon and raise Im K* channels, because positive K* ions are at higher concentration outside the axon than inside, and so they enter the axon and raise Vm K+ channels, because positive K* ions are at higher concentration inside the axon than outside, and so they leave the axon and lower Vm Submit
