Question

Which pair of peptides contained within the lateral hypothalamus is thought to increase eating?

1) insulin and CCK
2) serotonin and CCK
3) NPY and orexin
4) orexin and melanin-concentrating hormone
5) CCK and ghrelin

Answer 1

NPY and orexin are the pair of peptides contained within the lateral hypothalamus that is thought to increase eating.

Step-by-step explanation:

The pair of peptides contained within the lateral hypothalamus that is thought to increase eating is NPY and orexin. NPY (neuropeptide Y) is a potent appetite stimulant, while orexin (also known as hypocretin) regulates wakefulness and appetite. These two peptides work together to promote hunger and increase food intake.
