Based on Question 5: Know the typical electrical and concentration/chemical gradients that exist across the plasma membrane of a neuron for Na+, K+ and Cl-. Based on these gradients, be able to state what direction each ion moves across the membrane - -[Na+]out >> [Na+]in -[K+]out << [K+]in -Differences maintained by Na+ K+ ATPase pump; 3 Na+ ions out, 2 K+ ions in, creates a net loss of positive ions -resting membrane potential is -50 to -80 mV -for K+ and Cl-, concentration and...

NSC Chapter 5 Test with Complete Solutions transporters - Answer-special proteins embedded in the vesicle membrane that concentrate neurotransmitters inside the vesicle once the amino acid and amine neurotransmitters are synthesized in the cytosol and then taken up by the synaptic vesicles. voltage-gated calcium channels - Answer-following the depolarization of the terminal membrane, these channel proteins open and let in Ca++ ions; resulting elevation in the ions is the signal that causes n...
