Which of the following most accurately describes the effect ofyour drug treatment on action potentials?
A) Drug treatment inactivated voltage-gated sodium channelsleading to an extended relative refractory period
B) Drug treatment blocked voltage-gated potassium channelsleading to an extended relative refractory period
C) Drug treatment prolonged opening of voltage-gated potassiumchannels leading to an extended relative refractory period
D) Drug treatment prolonged opening of ligand-gated chloridechannels leading to an extended relative refractory period
You work in a lab that is developing new drug treatments. You are responsible for characterizing the drug's effects on action potentials. You record the action potential on the left before treating your neuron with your drug compound. Then, after treating your neuron with the new drug compound, you record the action potential on the right. You notice changes in stage 5 of the action potential.
