Which of the following is the most accurate description of why bitter and sweet tastants are perceived differently? a. The receptors for these classes of compounds are expressed in different cells. b. The receptors activate distinct second messenger systems. c. Bitter receptors are coupled to a different G-protein than sweet receptors. d. These tastants activate different parts of the tongue. e. Bitter is an inhibitory response, sweetness is activation.

A patient presents with the chief complaint of being unable to perceive “saltiness,” but they can perceive other flavors. From the image below, you propose the following pathway changes for sour perceptions as an explanation for these symptoms: A. The channels for Na+ were damaged B. Voltage-gated Ca2+ channels are not functioning C. There is no neurotransmitter release D. The afferent nerve is damaged E. All the above are viable pathway changes that would uniquely prevent the perception of salty
My question is Salty and sour taste molecules are transduced directly into an electrical signal using _________________________ while sweet, bitter, and umami tastes are transduced indirectly into an electrical signal using ________________________.
What is not true about fragrance reception? a) Odor receptor cells have G-protein coupled receptor mechanisms with high amplification b) We have about 400 varieties of fragrance receptors c) All scent impulses are perceived consciously d) Odor receptor cells are metabolized in a few months
Which of these flavors do not have specific receptors? a) sour b) salt c) sweet d) umami e) spicy
The taste of food goes to which area of the brain FIRST? a. Hypothalamus b. Medulla c. Parietal lobe of the cortex d. Limbic system
If you can taste only five things (salt, bitter, sweet, sour, umami), why do the many foods you eat all seem so distinct?
How do the Analgesic work for two pains? In other word, if we feel headaches with pain teeth we eat Panadol for both, so how Panadol knows the source of pain?
Which of the following statements about sensory systems is NOT true? a. Sensory transduction involves the conversion (by either a direct or indirect mechanism) of a physical or chemical stimulus into changes in membrane potential difference. b. Sensory adaptation plays a role in the ability of organisms to discriminate between important and unimportant information. c. The term "sensory adaptation" refers to the process by which a sensory cell becomes less sensitive, or less responsive, to a continuing source of stimulation. d. In general, a stimulus causes a change in the flow of charged ions across the plasma membrane of a sensory receptor cell. e. The more intense a stimulus is, the greater the peak depolarization of the action potentials fired by the sensory neuron.
A turkey ordorant molecule comes in contact with the pie ordorant receptor. Would this have an effect on the nerve stimulus being sent from this olfactory cell? Which G protein is activated in this pathway?
Do blind people dream in visual images? How can we differentiate so many different foods if we can only taste four flavors on our tongue: sweet, bitter, sour, and salty? Is human blood ever any color other than red? Why do camera flashes make your eyes turn red?
Compare the G protein Gs, which acts in transducing the signal from β-adrenergic receptors, and the G protein Ras. What properties do they share? How do they differ? What is the functional difference between Gs and Gi?
Which of the following happens in taste receptor cells when the membrane is depolarized by a receptor potential? a. Voltage-gated Ca?+ channels open, triggering the release of neurotransmitter. b. Voltage gated K+ channels open, triggering the release of neurotransmitter. c. Voltage-gated Ca?+ channels open, inhibiting the release of neurotransmitter. d. Voltage gated K+ channels open, inhibiting the release of neurotransmitter. e. Cyclic nucleotide gated ion channels open, increasing the release of neurotransmitter.
