Question

What will change if you permanently increase the extracellular K+ concentration? (more than one answer is possible)

a. the amplitude of action potential

b. the resting membrane potential

c. the membrane capacitance

d. the permeability of the neuron cell

e. the k+ conductance

Answer 1

The resting membrane potential and the permeability of the neuron cell will both change since an increase in K+ affects membrane potential and how substances can enter the neuron.
