12. Which of the following will occur after stimulating achemically-gated potassium channel located on the cell body of aneuron?
a.
potassium will enter into the cell body of the neuron andresults in generation of depolarizing graded potential
b.
potassium will exit out of the cell body of the neuron and thisresults in generation of depolarizing graded potential
c.
potassium will exit out of the cell body of the neuron and thisresults in generation of hyperpolarizing graded potential
d.
potassium will enter into the cell body of the neuron and thisresults in generation of hyperpolarizing graded potential
