Question

what taste sensation results when sodium ions enter gustatory cells through sodium ion channel receptors, and the cell depolarizes?
sour
bitter
umami
salty

Explanation:

When sodium ions (\(Na^+\)) enter gustatory cells through sodium ion channel receptors and cause depolarization, it is associated with the sensation of saltiness. Sour taste is related to hydrogen ions (\(H^+\)), bitter taste has complex mechanisms involving various receptors, and umami is associated with glutamate and other amino - acid related compounds.

Answer:

Salty
