You are working on a new medication to selectively kill cancer cells. You test the drug on a culture of normal neurons to check for any side effects. Despite the presence of the drug, a normal resting membrane potential of -70 mV is maintained. Look at each of the figures below to analyze how the drug might be affecting the neuron. Figure A shows neuron activity under normal, or control, conditions (without the drug). Figure B shows neuron activity that has been altered due to exposure to the drug. Based on these results, the drug is most likely _____. destroying some of the Na^+ leak channels opening voltage-gated K^+ channels destroying some of the K^+ leak channels preventing Na^+ -gated channels from opening

Solution

answer:

opening voltage gated K+ channel

when the drug shows the result in cell membrane its must be there some of ion chanells exchange like a Na and K ions then only any drug enter into the membrance and binds with the receptors then only its shows the results

so when the voltage gated K+ channels are entered into the membrane there is no chance to to ions transportaion so there is no action finnaly the neuron action will be flot
