Question

Quizplus · Accepted Answer

Sour receptors are triggered by the direct effect of hydrogen ions on sodium channels. When the pH of a substance is low (meaning it is acidic), it causes an influx of positively charged hydrogen ions into the taste cells. These hydrogen ions then bind to and block potassium channels, depolarizing the cell and causing an action potential that signals to the brain that the food is sour.
