Which is not a difference between tasting salty versus bitter? Saltiness has a higher threshold to taste than bitterness. Saltiness generates a receptor potential by direct flow of ions into the receptor, while bitterness involves gustducin proteins and IP3 messenger proteins. Saltiness has been more important in human evolution due to the risks of ingesting too much salt. Saltiness is caused by ions, while bitterness is caused by substance with a basic pH.
