1 The process of translating the sensation received into neural messages that the brain can comprehend. 2  Transduction = translation. 3  The process of information getting transduced into nerve cells. 4  Transduction occurs with all five senses, Taste, Smell, Hearing, [[#|Sight]], and Touch. Transduction occurs with all five senses, Taste, Smell, Hearing, [[#|Sight]], and Touch. 2  In the ear it occurs in the cochlea, in the nose it occurs in the taste buds, and in hearing it occurs in the inner ear.
Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. In turn, this receptor triggers a biochemical chain of events inside the cell, creating a response.Depending on the cell, the response alters the cell's metabolism, shape, gene expression, or ability to divide. The signal can be amplified at any step. Thus, one signaling molecule can cause many responses.his results in either the activation of an enzyme domain of the receptor or the exposure of a binding site for other intracellular signaling proteins within the cell, eventually propagating the signal through the cytoplasm.
