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

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.
