Sour receptors detect the protons (H +) liberated by sour substances (acids). This closes transmembrane K + channels which leads to depolarization of the cell [ Link ], and the release of the neurotransmitter serotonin into its synapse with a sensory neuron.umans detect taste with taste receptor cells. These are clustered in taste buds and scattered in other areas of the body. Each taste bud has a pore that opens out to the surface of the tongue enabling molecules and ions taken into the mouth to reach the receptor cells inside. 1  salty. 2  sour. 3  sweet. 4  bitter.
Receptors. Receptors are groups of specialised cells. They can detect changes (stimuli) in the environment. Receptors are often located in the sense organs, such as the ear, eye and skin.Each organ has receptors sensitive to particular kinds of stimulus. The table shows some receptors and the stimuli they detect.he sense organs contain receptors that are sensitive to stimuli. The nervous system consists of the central nervous system-brain and spinal cord-and peripheral nerves. Nerve impulses travel through the axons of neurones-nerve cells.
