Answer:
That's correct. Voltage-gated channels are ion channels that open or close in response to changes in the membrane potential. This allows for the flow of ions across the membrane, which can change the membrane potential and trigger action potentials. Passive channels, on the other hand, are always open and allow ions to flow across the membrane in a passive way, without any input from the cell.
Voltage-gated channels are important for neural signaling because they allow for the rapid and efficient transmission of information between neurons. Passive channels are also important, but they play a more supporting role in neural signaling.
