Abstract
Using the patch‐clamp technique, we demonstrate here the opening of K+ channels evoked by the actively transported amino acid L‐alanine in isolated Necturus enterocytes. These channels had a conductance of about 30 pS and their activation was dependent on transmembrane electrical potential and cytosolic Ca2+.Keywords
