 Voltage-gated ion channels

Voltage-gated ion channels are specialized proteins found in the cell membrane that open or close in response to changes in the membrane potential (voltage). They play a crucial role in the generation and propagation of electrical signals in excitable cells, such as neurons and muscle cells. Here are key features of voltage-gated ion channels: 1. **Voltage Sensitivity**: These channels have a voltage sensor that detects changes in the electrical charge across the membrane.
