Which of the following statements about olfactory receptors is not true? A Stronger odours cause more olfactory receptors to respond or fire than weaker odours do. B) The axons of the olfactory receptor cells reach directly into the brain c) There are at least 1000 different types of olfactory receptors for different odours D Olfactory neurons last a lifetime, and cannot be replaced once they are destroyed

Which of the following statements is true regarding olfactory information? the olfactory receptors are located in the olfactory bulb the glomeruli are organized by connections with specific olfactory receptor types the olfactory tract axons go directly to the orbitofrontal cortex odorants are detected on the cell bodies of the olfactory receptors
Which of the following statements about the olfactory system is true? Question 2 options: Turbinates are always in motion to sweep odorants up to the olfactory epithelium. All odorants must reach the olfactory epithelium through the nose. The two nasal cavities sample different sections of air providing a binasal experience. Olfactory receptor neurons die after about a month and must be resupplied.
A 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.
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.

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). If you plug your nose, red wine and coffee taste exactly the same. Explain why this is so.
