Transcript text: In weight control Serotonin may influence levels of $\qquad$ to regulate feeding behavior
Solution
The answer is NPY.
Explanation for each option:
NA; Potassium: This option is incorrect. Serotonin does not primarily influence potassium levels to regulate feeding behavior. Potassium is an essential mineral involved in various bodily functions, but it is not directly linked to the regulation of feeding behavior through serotonin.
NPY: This option is correct. Neuropeptide Y (NPY) is a neurotransmitter that is known to play a significant role in regulating feeding behavior and energy balance. Serotonin can influence the levels of NPY, thereby affecting appetite and feeding behavior.
Dopamine: This option is incorrect. While dopamine is involved in reward and pleasure pathways, which can influence eating behavior, it is not the primary neurotransmitter influenced by serotonin for the regulation of feeding behavior.
PYY: This option is incorrect. Peptide YY (PYY) is a hormone involved in reducing appetite, but it is not directly influenced by serotonin in the context of regulating feeding behavior.
In summary, serotonin may influence levels of NPY to regulate feeding behavior.
