The diagram above depicts the signal transduction pathway of the sweet taste. Object A is a taste bud, object B is one taste cell of the taste bud, and object C is the neuron attached to the taste cell. I. Part I shows the reception of a molecule. 1. Sugar, the first messenger, binds to a protein receptor on the cell membrane. II.
Bitter taste has many different receptors and signal transduction pathways. Object A is a taste bud, object B is one taste cell, and object C is a neuron attached to object B. I. Part I is the reception of a molecule.1. A bitter substance such as quinine, is consumed and binds to G protein-coupled receptors.II. Part II is the transduction ...
Gustducin is a G protein associated with taste and the gustatory system, found in some taste receptor cells. Research on the discovery and isolation of gustducin is recent. It is known to play a large role in the transduction of bitter, sweet and umami stimuli. Its pathways (especially for detecting bitter stimuli) are many and diverse.
TAS2Rs activation produces modulation of a broad range of signal transduction pathways. The Gαgusducin (Gαgus), which belongs to the Gαi subfamily, was first identified and cloned in 1992 in taste tissue, and has high similarity to the Gα-transducin (Gαtrans) in the retina. Gα16gus44, a chimeric Gα16 (type of Gαq), harboring 44 ...

In physiology, transduction is the translation of arriving stimulus into an action potential by a sensory receptor. It begins when stimulus changes the membrane potential of a sensory receptor . A sensory receptor converts the energy in a stimulus into an electrical signal. [ 1 ]

TAS2R38 is a bitter taste receptor; varying genotypes of TAS2R38 influence the ability to taste both 6-n-propylthiouracil (PROP) [5] and phenylthiocarbamide (PTC). [6] [7] Though it has often been proposed that varying taste receptor genotypes could influence tasting ability, TAS2R38 is one of the few taste receptors shown to have this function ...
