Question

After depolarization, the _________channels close and __________channels open. This allows _________to flow _______the cell which makes the inside of the neuron more _________. This action is called __________ and returns the membrane potential to ________ mV, at which point the _________ channels close

Answer 1

The correct term to fill in the blank would be voltage dependent channels. Channels in the membrane of the neuron allow ions to flow between the inside and outside of the cell. of these, voltage dependent channels open only when certain electrical conditions are met. These channels are transmembrane proteins that are activated by the changes in the electrical potential near it. The electric potential would alter the conformation of the proteins which in turn would regulate the closing and opening of the channels. The change in the electric potential is called the depolarization. Most of these channels are ion-specific like for the ions, calcium, sodium, chloride and potassium.
