Question

which sensation of taste is sensitive to the potential of hydrogen (ph; presence of hydrogen ions h⁺)?
○ umami
○ sweet
○ sour
○ salt

Explanation:

Sour taste is associated with the presence of hydrogen ions (\(H^+\)). The pH scale measures the concentration of \(H^+\) ions. A lower pH (more acidic) is detected as a sour taste. Umami is related to savory substances like glutamate, sweet to sugars, and salt to sodium chloride.

Answer:

C. Sour
