Appetite suppressors are all EXCEPT :: (A) Melanocyte stimulating hormone, (B) Melanocyte corticotropic releasing hormone, (C) Neuropeptide Y, (D) Leptin
Answer is C. Alpha-Melanocyte-Stimulating Hormone (alpha-MSH) and corticotropin-releasing hormone (CRH) both suppress food intake.
NPY is known to be an extremely potent stimulator of feeding behavior.
Leptin appears to act, at least in part, by inhibiting NPY synthesis and release in the hypothalamus.
