10 points Save Answer are a delicacy in Japan, but must be cleaned very carefully as their liver contains tetrodotoxin which blocks voltage -gated Na+ channels Imagine you are testing for the a stimulus to the nou on that should produce an actin potential presence of this toxin using a neuron in a dish You hat will you obser to block the neuron’s voltage-gated Na+ channels? o The neuron will exhitbt a slow depolarication even before the stimuus is applied folowed by a normal action potentl o The neuron will exhiblt a slow hyperpolarization even before the stimulus is applied The neuron wll show a normal resting potential, but vill not exhibil depolarization when the stimulus is applied O The neuron will exhibit rapid depolariz ation, but will not repolarize O The neuron ㆋ depolarize normally, but then become hypepolarized such that the membrane potential is much lower than usual tetro otoon levels are high enough QUESTION 8 10 points Save Answer Action potentials move along axons O more slonly in axons of large diameter as compared to those of small dameter O by the direct action of acetylcholine on the axonal membrane o by activating the sodium-potassium “pump at each point along the axonal membranse o more rapidly in myelinated than in nonmy elinated axons by reversing the concentration gradients for sodum and potassium ions QUESTION9 10 points Save Answer Afer an action potential is triggered, the rapid increase in membrane potential can be attributed to the closing of sodium leak channels O the closing of potassium leak channels O the direction reversal of the sodium/potassium pump the opening of the voltage gated sodium channels the opening of the voltage-gated potassium channels
