Explanation / Answer

1) The neurotransmitter binds to postsynaptic membrane. An electric current is generated that changes postsynaptic membrane potential to more negative.

b) The neurotransmitter causes EPSP

c) The amplitude of the EPSP is directly proportional to the number of synaptic vesicles which are released. The rest values are needed to exactly calculate the volts.
