If we excite a motor neuron to fire an action potential in the presence of EGTA to complex all of the Ca2+
A) Acetylcholine release will be reduced and the EPP will be reduced, but the muscle will contract B) Neurotransmission will be unaffected but contraction will be blocked because it requires Ca2+ C) Neurotransmission will be blocked and so there will be no contraction D) Neurotransmission block can be overcome by repetitive stimulation E) The neuron cannot fire an action potential in the absence of Ca2+
