Predict the Expected Consequence(s)of Applying a Toxin That Blocks Voltage-Gated

question 37

Multiple Choice

Predict the expected consequence(s) of applying a toxin that blocks voltage-gated Ca²⁺ channels in a neuron.

• A)No resting membrane potential would be observed (i.e. ,measures at 0 mV).
• B)A rapid increase in membrane potential at threshold voltage would not occur.
• C)Membrane potential would increase rapidly to peak with an action potential,but would not decrease immediately afterwards.
• D)The neuron would become hyperpolarizeD.
• E)Neuron conducts action potentials normally,but would not transmit these potentials across chemical synapses.
