Object A is a taste bud, object B is a taste receptor cell within object A, and object C is the neuron attached to object B. I. Part I is the reception of hydrogen ions or sodium ions. 1. If the taste is sour, H+ ions, from an acidic substances, pass through their specific ion channel. Some can go through the Na+ channels.
Taste buds and papillae of the human tongue Taste receptors of the human tongue Signal transduction of taste receptors. Taste is a form of chemoreception which occurs in the specialised taste receptors in the mouth. To date, there are five different types of taste these receptors can detect which are recognized: salt, sweet, sour, bitter, and ...
The five basic tastes (saltiness, sweetness, bitterness, sourness, and savoriness) are detected by specialized taste receptors on the tongue and palate epithelium. [59] The number of taste categories in humans remains under research, with a sixth taste possibly including spicy or pungent.

The gustatory cortex is the primary receptive area for taste. The word taste is used in a technical sense to refer specifically to sensations coming from taste buds on the tongue. The five qualities of taste detected by the tongue include sourness, bitterness, sweetness, saltiness, and the protein taste quality, called umami.
Animals, specifically humans, typically have five different types of tastes: sweet, sour, salty, bitter, and umami. The differing tastes are important for distinguishing between foods that are nutritionally beneficial and those which may contain harmful toxins. [69]
Sour foods include citrus, specifically lemons, limes, and to a lesser degree oranges. Sour is evolutionarily significant as it is a sign of food that may have gone rancid due to bacteria. [27] Many foods, however, are slightly acidic and help stimulate the taste buds and enhance flavour.
Certain foods just taste better than others, and usually, they’re the ones that have sugar and fat—at least in our experience. Now, a new study explains why it can be so tough to resist ...
