Electrogenic
Definition:
(a.) Of or pertaining to electrogenesis; as, an electrogenic condition.
Example Sentences:
(1) An electrogenic sodium-potassium pump appears to contribute materially to the steady-state potential and to certain of the transient potential responses of vascular smooth muscle.
