QUESTION 1 How will a neuron respond to an injection of negative current? a.It will become hyperpolarized. D It will have a positive electrical response. OC It will generate a single action potential Od It will generate multiple action potentials. 0 e. It will reach the threshold potential. QUESTION 2 In a two-compartment model of a cell with a K -permeable membrane, at K of Kt ions. equilibrium potential, there is flux O a a large inward a large outward C no net O d a small inward e a small outward

Explanation / Answer

Correct Answer - A

As the resting potential of a neuron is in the negative at about -70 mV, an injection of negative current will make it more negative, which is called hyperpolarization. If the current would be a positive current then it would generate an action potential if the charge would exceed the threshold.
