1.1 What would be the effect of blocking neurotransmitter degradation on neurotransmitter concentration at the synapse? 1.2 You are studying an excitatory synapse that is not strong enough to evoke a postsynaptic action potential. Would the probability of a postsynaptic potential increase or decrease after blocking neurotransmitter degradation? 1.3 You are studying an excitatory synapse that evokes a postsynaptic action potential. Would the probability of a postsynaptic potential increase or decrease after blocking presynaptic voltage-gated calcium channels?

Step 1
1) Blocking neurotransmitter degradation would prevent the breakdown of neurotransmitters in the synaptic cleft. As a result, the concentration of neurotransmitters at the synapse would increase. Answer: $\boxed{\text{Increased neurotransmitter concentration}}$ Show more…

One way of decreasing the number of synaptic vesicles released from presynaptic terminals of motor neurons by an action potential would be to: Decrease extracellular calcium levels Prolong the action of Acetylcholinesterase Keep the voltage-gated calcium channels open for longer periods of time Block nicotinic acetylcholine receptors

12. What part of the neuron acts as the final integrating center for all of the incoming graded potentials? What has to occur for the neuron to generate an action potential? 13. Think of situations in which it is important for the postsynaptic neuron or effector (muscle or gland) to be stimulated (EPSP). Then consider situations in which inhibition (IPSPS) would be important. What kinds of problems might occur if it were not possible to create IPSPS? (For example, what if postsynaptic cells were always stimulated?)

While observing a post-synaptic neuron that receives input from many pre-synaptic neurons, you notice that, regardless of other input, the post-synaptic cell always has an action potential when one particular synapse is active. Which of the following is most likely true about this synapse? a) It is an excitatory axo-axonic synapse. b) It is an inhibitory axo-axonic synapse. c) It is one of several synapses close to the axon hillock. d) The presynaptic neuron at this synapse is tonically active.
