satiety would be induced by all of the following EXCEPT
a. cholecystokinin
b. naloxone
c. morphine
d.seratonin
I know its not a or c, because those induce satiety. I'm stuck between b and c ...i think its b though
You are correct that cholecystokinin and serotonin induce satiety. Out of the options given, naloxone is the one that does not induce satiety. Therefore, the correct answer is b. naloxone.
To determine the answer to this question, let's go through each option and see whether it is associated with inducing satiety or not.
a. Cholecystokinin (CCK): CCK is a hormone that is released by the small intestine in response to the presence of fat and protein in the digestive system. It is known to induce satiety, causing a decrease in appetite. Therefore, option a is associated with inducing satiety.
b. Naloxone: Naloxone is a medication that is commonly used to reverse the effects of opioid drugs. It works by blocking the opioid receptors in the brain. Naloxone, by itself, does not induce satiety or affect appetite. Therefore, it is a possibility for the correct answer.
c. Morphine: Morphine is an opioid drug that acts on the central nervous system. Opioid drugs are known to suppress appetite and induce satiety. Therefore, option c is associated with inducing satiety.
d. Serotonin: Serotonin is a neurotransmitter that has various functions in the body, including the regulation of appetite and mood. It is known to play a role in satiety and can decrease hunger. Therefore, option d is associated with inducing satiety.
Based on the explanations above, the only option that is NOT associated with inducing satiety is b. Naloxone. Therefore, the correct answer is option b.
