Synapses Study Questions (Select the single BEST answer) 1. Which below lists the events occurring at the synapse in the proper order? A) action potential in synaptic knob, opening of synaptic knob Ca ++ channels, transmitter release into synaptic cleft, binding of transmitter to receptors on subsynaptic membrane, postsynaptic potential in postsynaptic cell B) opening of synaptic knob Ca ++ channels, transmitter release into synaptic cleft, action potential in synaptic knob, postsynaptic potential in postsynaptic cell, binding of transmitter to receptors on subsynaptic membrane C) transmitter release into synaptic cleft, binding of transmitter to receptors on subsynaptic membrane, postsynaptic potential in postsynaptic cell, opening of synaptic knob Ca ++ channels, action potential in synaptic knob D) action potential in synaptic knob, transmitter release into synaptic cleft, opening of synaptic knob Ca ++ channels, binding of transmitter to receptors on subsynaptic membrane, postsynaptic potential in postsynaptic cell 2. The way neurotransmitters move across the synaptic cleft (to bind with receptors on the postsynaptic cell) is by A) active transport B) diffusion C) both A and B D) neither A nor B 3. Which below is a way to prevent a neurotransmitter from restimulating a postsynaptic neuron? A) neurotransmitter could be broken down by enzymes B) neurotransmitter could be taken back up into the presynaptic neuron C) both A and B D) neither A nor B 4. Which of the following is NOT associated with inhibitory postsynaptic potentials (IPSPs)? A) GABA B) depolarization C) increased K + permeability 5. An action potential occurs in the postsynaptic neuron if A) an EPSP occurs B) an IPSP occurs C) Na + permeability increases D) the neuron membrane is depolarized to threshold 6.
