You generate action potentials in a neuron bathed in solution in a petri dish by applying a threshold-level depolarizing stimulus near its axon hillock. If the solution surrounding the neuron contained 5mM K+, 150 mM Na+, and 0 mM Ca2+ which of the following would you expect? The neuron would not be able to propagate action potentials down the entire length of the axon O The neuron would not release neurotransmitter from the axon terminal O The neurons action potentials would have an unusually long duration O The neuron would have a resting membrane potential of zero
