B Postsynaptic membrane Postsynaptic Transmitter molecule membrane attaches to receptor site depolarizes Movement of ions Receptor site through membrane a) i) List the events 1-6 in the correct sequence of events. i) Name the ions labelled A and B. " iii) By what process do transmitter molecules move across the synaptic cleft? iv) Name one transmitter molecule released by synaptic vesicles in the brain. b) One impulse arriving at the presynaptic membrane does not produce an action potential in the postsynaptic membrane, but several impulses arriving in succession do. i) Explain this observation ii) What name is given to the process described?
