Students have asked these similar questions
Many odorant molecules are highly hydrophobic and concentrate within the olfactory epithelium. 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.

- The olfactory system has many receptor types but the transduction process is very similar in each receptor type. 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_forwardBriefly explain the difference between a receptor antagonist and a receptor inverse agonist. Describe both the resulting receptor conformation as well as the signal transduction.arrow_forwardIn the olfactory receptor cells of mammals, what binds to specific odorant molecules?arrow_forward
- In most neurons, membrane depolarization leads to the opening of voltage-dependent ion channels, generation of an action potential, and, ultimately, an influx of Ca2+, which causes release of neurotransmitter at the axon terminus. Devise a cellular strategy by which hyperpolarization in rod cells could produce excitation of the visual pathway and passage of visual signals to the brain. (Hint: The neuronal signaling pathway in higher organisms consists of a series of neurons that relay information to the brain. The signal released by one neuron can be either excitatory or inhibitory to the following, postsynaptic neuron.)arrow_forwardDiscuss the location and activation of olfactory receptors and how the brain distinguishes tens of thousands of odours from 1,000 or fewer receptor proteins.arrow_forwardA mixture of two of the compounds illustrated in Figure 33.6 is applied to a section of olfactory epithelium. Only receptors 3, 5, 9, 12, and 13 are activated, according to Figure 33.7. Identify the likely compounds in the mixture.arrow_forward
- When light hits a retinal molecule bound to the rhodopsin, the retinal molecule changes its conformation, going from a cis- configuration to an all-trans configuration (see figure below). This forces the rhodopsin receptor to also undergo a change in its conformation and become activated. 11-cis isomer ** Light Retinal is therefore a key player that triggers a series of activation in phototransduction (see figure below).

Light hits the retinal molecule and changes into an all-trans configuration 2. This change in the retinal conformation activates the rhodopsin photoreceptor 3. The rhodopsin photoreceptor then activates a specific heterotrimeric G protein called transducin. 4. The transducin then activates a…arrow_forwardIn olfactory neurons, it is estimated that activation of the olfactory receptors results in an increase of roughly 200,000 molecules of cAMP per second. 1a) If an activated receptor produces one molecule of cAMP every 30 seconds, how many molecules of this receptor must be working in an activated neuron? How many G-alpha subunits are required in an activated neuron? 1b) If one receptor molecule is capable of activating 500 G-proteins, how many receptors will be activated?arrow_forwardCompare the mechanisms of the receptor molecules for salty and sour taste; the taste-receptor molecules for sweetness, bitterness, and umami; and odor-receptor molecules (Indicate if a given sense uses a GPCR, an ion channel etc and how the downstream signal might be different).
