Each hormone is a signal for the cell, that a specific chemical reaction must be done.
As the molecules of hormones attach to cell receptors, adenylyl cyclase (transmembrane protein) is activated. Activated Adenylyl cyclase modifies ATP to form cyclic adenine monophosphate (cAMP). cAMP then activates various enzymes that catalyse the necessary reaction. Therefore, cAMP is an intermedium between the hormone and the result (chemical reaction).

BlakecAMP (cyclic adenosine monophosphate) acts as a second messenger in hormone signaling pathways. It amplifies the hormonal signal inside the cell by activating protein kinase A, which in turn phosphorylates target proteins to regulate various cellular processes like gene expression, metabolism, and cell growth.

How hormones function in a reflex arc?
Hormones have nothing to do in reflex arc.
Who discovered cyclic AMP?
Cyclic AMP (cAMP) was discovered by Earl Wilbur Sutherland Jr., an American pharmacologist, in 1957. He received a Nobel Prize in 1971 for his discoveries related to the mechanisms of action of hormones.
What role does cyclic AMP play for most hormones?
Cyclic AMP (cAMP) serves as a second messenger for many hormones. When hormones bind to their specific receptors on the cell membrane, it triggers a cascade of biochemical events that lead to the production of cAMP. cAMP then activates other signaling molecules, such as protein kinase A, which regulate various cellular processes, including gene expression, metabolism, and cell growth.
Why are tropic hormones so called?
Tropic hormones are named for their action on other endocrine glands. Their primary function is to stimulate the secretion of hormones by target glands in a sequence known as the hypothalamic-pituitary-target gland axis. These hormones regulate the activity of other endocrine glands and help maintain homeostasis in the body.
What is the chemical substance that affects the function of cells elsewhere in the body?
hormones
