Endorphins are a type of short strings of amino acids that are narrowly targeted to perform a specific job. for instance, endorphins specialize in reducing pain.

Endorphins are a type of neuropeptides short strings of amino acids that are narrowly targeted to perform a specific job. For instance, endorphins specialize in reducing pain.

Explanation:

Endorphins are opiod neuropeptides that are produced by the central nervous system. They are natural pain killers that are produced by our body to reduce pain.

They are of 3 types namely, alpha endorphins, beta endorphins and gamma endorphins. All of these specifically bind to the opioid receptors inhibiting the communication of pain signals.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
