electrogenic transport

Electrogenic transport refers to a process where a transporter protein moves ions across a cell membrane, creating an imbalance of electrical charge. This means it moves a different number of positive or negative charges in or out of the cell, generating an electrical current. For example, some transporters move two positive ions in for every one negative ion out, resulting in a net electrical charge movement. This process is essential for maintaining cell function, nerve signaling, and energy production, as it helps establish the electrical gradients necessary for various physiological activities.
