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 neurotransmitter is detected since influx of calcuim into the synaptic knob is required for neurottransmitter releaseB. No neurotransmitter is detected since influx of calcuim 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
