Problem set for lecture 6: Synaptic Transmission Reading Assignment: Bear et al. Chapter 5. C. Questions - Test_06: 1. Quantal analysis shows that a single action potential at the neuromuscular junction causes an EPSP of 40 mV or more as against only a few tenths of a millivolt at many CNS synapses. What accounts for this difference? Choose the correct option. A) A larger number of synaptic vesicles releasing neurotransmitter at the neuromuscular junction compared with CNS synapses B) A larger number of transmitter molecules within the synaptic vesicles of a motor neuron compared with CNS synapses C) Larger receptors at the neuromuscular junction compared with CNS synapses D) A larger synaptic cleft at neuromuscular junction compared with CNS synapses 2. What are transporters? What is their role? Choose the correct option. A) Enzymes that synthesize neurotransmitters from metabolic precursors; responsible for concentrating neurotransmitters in the synaptic cleft B) Synthesizing enzymes for both amino acid and amine neurotransmitters; responsible for concentrating neurotransmitters inside the vesicle C) Special proteins embedded in the vesicle membrane; responsible for synthesizing neurotransmitters
