Hormons are known as chemical messenger justify.

Explanation

Hormones are chemical messengers because they act as organic catalysts and coenzymes to perform specific functions in the target organs. The target organs contain receptor molecules either on the surface or within the cell. Although different hormones come in contact with cells, only the celis that contain receptor molecules specific for the hormone are physiologically activated. A single hormone may have multiple effect on a single target tissue or on different target tissues.
