1a. all of the following are true about nerons except... (A. they produce ATP by cellular respiration, B. they are found in the central and peripheral nervous system, C. they have Na+/K+ pumps in their membranes, D. they can rapidly depolarize, E. they don't contain nucleir or mitochondria
1b. a reesting potential of -70mV ...(A. is possible because of voltage-gated sodium channels, B. is possible because of ligand-gated sodium, C. means that the outside of the neuron is more negative than the inside, D. is an IPSP that leads to threshold potential)
1c. after an action potential is triggered, the rapid increase in membrane potential to +50mV can be attributed to (A. opening of voltage-gated sodium channels, B. reversal of the direction of the sodium/potassium pump, C. opening of voltage-gated potassium, D. closing of ligand-gated potassium channels)
