Eeob 4550 exam 1 and 2 - Study guides, Class notes & Summaries

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...
