Quizplus · Accepted Answer

Hormones are chemicals produced by the endocrine system that regulate a variety of body functions, such as metabolism, growth and development, and reproductive processes. They are not specifically stimulated by the action of metabolic enzymes, although certain enzymes may be involved in their synthesis and degradation. Hormones travel through the bloodstream to specific target cells, where they bind to receptor molecules and elicit a response.
