- Five different types of taste receptors have been identified in humans. These are salty, sour, sweet, bitter and umami. Taste receptors consist of specific types of proteins incorporated into the plasma membrane of taste receptor cells, which are clustered together in structures called taste buds. All five receptor types are present in each taste bud, which are distributed over most of the tongue surface area. Olfactory receptors are located in the nasal cavity and consist of several thousand different types, each type specific for a different odorant molecule (ligand). You may need to research this on the internet. Be sure to site your sources. If you plug your nose, red wine and coffee taste exactly the same.arrow_forwardFive different types of taste receptors have been identified in humans. These are salty, sour, sweet, bitter and umami.

They would give a persistent signal independent of their concentration in the environment if they were not rapidly modified. Propose a mechanism for converting hydrophobic odorants into watersoluble derivatives that can be rapidly eliminated.arrow_forward

What do these transduction processes all have in common? They all use G protein-coupled receptors. They are all linked to a particular gustatory (taste) receptor type. O They all use ionotropic receptors. O They all involve temporarily hyperpolarizing the receptors, rather than depolarizing them.arrow_forwardIn the olfactory receptor cells of mammals, what binds to specific odorant molecules?arrow_forward
- Listed below are the various components of the olfactory transduction process: 1. Golf G-protein 2. Voltage-gated sodium channel 3. Calcium-activated chloride channel 4. CAMP-gated ion channel 5. Adenylyl cyclase Which of the following is the correct order in which these components are activated? 2; 1; 5; 4; 3 5; 1; 4; 3; 2 1; 5; 4; 2; 3 3; 2; 1; 5; 4arrow_forwardA specific pattern of activation is observed in the right hemisphere piriform cortex in response to a specific smell. Which of the following choices must be true? Group of answer choices a - The pattern of activation across the glomeruli in the left olfactory bulb mirrors the pattern of activation observed in the right hemisphere piriform cortex. b - The activity in the right hemisphere piriform cortex was independent of the number of odorant molecules that entered the olfactory epithelium. c - The odorant molecules that made up the smell were of different shapes and therefore activated different receptors in the right nostril, creating a unique pattern that is conserved first across the olfactory bulb, then along the olfactory tract, then within the thalamus, and then finally in the right hemisphere piriform cortex. d - The activity in the right hemisphere piriform was initiated by the binding of odorant molecules to G-protein coupled receptors in the right nostril.arrow_forwardReceptors within the olfactory epithelium in the nasal cavity project to the glomeruli, which project to the mitral cells, which project as cranial nerve one to the pyriform and the entorhinal cortex located in the anterior and medial temporal lobe. What's odd about this sensory pathway, unlike other sensory pathways? Select one: a. it does not show sensory adaptation b. there is no thalamic nuclei processing olfactory infomation prior to processing in the primary cortex c. loss of smell can be a result of damage to the temporal lobe or damage to the olfactory receptor cells d. it processes information ipsilaterally e. the primary olfactory cortex is not part of the telencephalonarrow_forward
