Since hormones are present in such small amounts, how can their signals be amplified enough to
regulate so many physiological processes? What will be an ideal response?
Concepts to Consider: Through signal amplification, a single hormone-receptor complex can activate
the production of many cyclic AMP molecules. Each of these can then activate a protein kinase, which
phosphorylates many protein molecules. Thus, one hormone molecule can stimulate many proteins.
