A neuron is placed in a dish with the appropriate medium. What would happen to
the resting membrane potential if the sodium-potassium pumps are blocked?
a.Increase (a greater negative charge- hyperpolarization)
b.Decrease (a smaller negative charge- depolarization)
c. No change from the resting membrane potential when the pump is active
d.It would not reach the normal resting membrane potential - answ✔️💜💜✔️d. It would
not reach the normal resting membrane potential
Does the resting membrane potential increase or decrease if we decrease the
concentrations of extracellular K+?
a.Increase (a greater negative charge- hyperpolarization)
b.Decrease (a smaller negative charge- depolarization)
