Answer to Question 1

C
All body cells have receptors for neuropeptides, which are amino acids that are produced in the brain and other body sites and act as chemical communicators. Neuropeptides are released when neurotransmitters, which are chemical substances that are produced by the body and facilitate nerve-impulse transmission, signal emotions to the brain.

Answer to Question 2

All body cells have receptors for neuropeptides, which are amino acids that are produced in the brain and other body sites and act as chemical communicators. Neuropeptides are released when neurotransmitters signal emotions to the brain.
