In order for a nerve impulse to be transmitted across the synapse, the amount of excitatory neurotransmitter must exceed that of inhibitory neurotransmitter by an amount called the “threshold.” Which of the following combinations will result in the firing of a neuron whose threshold is 120 units? AMOUNT OF NEUROTRANSMITTER RELEASH NEURON TYPE OF NEURON V Inhibitory 100 units W Inhibitory 50 units x Excitatory 100 units Y Excitatory 75 units Z Excitatory 25 units O V and W O Y and Z W. X and Y O V. X and Y What would occur if a chemical blocked the action of acetylcholinesterase? Synaptic endings would continue to release neurotransmitters. O Nerve transmission would last for an abnormally long time. The synaptic vesicles would not fuse with the presynaptic membrane. O Nerve transmission would end immediately.
