An investigator places as isolated neuron in a calcium-free medium, gives the neuron a suprathreshold stimulus and then performs an assay to test whether neurotransmitter is released into the medium. Which of the following outcomes would you predict ?A. No neurotansmitter is detected since influx of calcium into the synaptic knob is required for neurotransmitter releaseB. No neurotransmitter is detected since influx of calcium is required in order for the neuron to conduct an action potentialC. Neurotransmitter is detected since calcium is not required for action potential conduction and the initial stimulus was suprathresholdD. We cannot predict the outcome without knowing whether the neuron was myelinated
