Answer :
If a potassium leak channel inhibitor is applied to a culture of neurons the resting membrane potential would become more positively charged.
Since they control intracellular and extracellular ionic concentrations and produce resting or action potentials, ionic channels in neurons are essential. In contrast to the action potential, which always happens after this, the resting potential makes the neuron appear inactivated when conveying a signal and does not take stimuli from others. The resting potential would be extended and would possibly approach total rest for a long time if the potassium channels of a neuron were to remain closed. High levels of neuronal intracellular potassium prevent action potentials from being triggered, hence this neuron would not experience a membrane action potential, cause muscular contractions, or transmit signals.
