Quizplus · Accepted Answer

Sour and salt tastes are not mediated by G-protein coupled receptors. Sour taste detection involves ion channels that detect the hydrogen ions in acids, while salt taste primarily involves the direct passage of sodium ions through ion channels. Sweet and bitter tastes, on the other hand, are mediated by G-protein coupled receptors.
