Question: How do salty taste receptors transduce stimuli into neural signals? Need Assignment Help? By activating G-protein coupled receptors which then initiate a signaling cascade. By the entry of sodium ions through ion channels, leading to depolarization of the taste cell. By the conversion of salt molecules into electrical signals through enzymatic reactions. By the binding of salt molecules to receptor proteins that activate a secondary messenger system. By decreasing the release of neurotransmitters into the synaptic cleft.
