Vedclass · Answer

(D) Hormones are chemical messengers that are secreted by endocrine glands directly into the blood to act on target organs.$Thyroxine$ is a hormone produced by the thyroid gland that regulates metabolism.Unlike enzymes,which are biological catalysts that speed up chemical reactions without being consumed,hormones act as signaling molecules that regulate physiological processes.While enzymes are often proteins,hormones can be proteins,peptides,or amino acid derivatives (like $Thyroxine$,which is an iodinated amino acid).The primary distinction is functional: enzymes catalyze reactions,whereas hormones regulate them by binding to specific receptors.

Why is $Thyroxine$ considered a hormone and not an enzyme?
