Frequently asked question (faqs) on the mechanism of action of hormone. q.1. what do you mean by hormone action? ans: hormone action refers to the release and activity of hormones on the target cell. hormone activates the target cell by binding to the receptor and causing a chain of biochemical events that manifests in physiological response. To better understand the mechanism of hormone action, it is crucial to comprehend various definitions. hormone action. a hormone is a tiny chemical messenger, travelling along with the bloodstream. it exists to maintain internal balance or in other words, keeps the human body in a state of homeostasis. The hormones help in the growth, metabolism, development, reproduction, and secretion of fluids. the mechanism of hormone action will start at a certain time and keep working over a continuous period of time. a few important hormones of the human body are insulin, thyroid hormones, estrogen, progesterone, testosterone, and serotonin. The hormones that are protein or amines in compositions such as growth hormone, adh, oxytocin, insulin, adrenaline, fsh, tsh etc shows this mechanism of action. these hormones are water soluble and cannot passes through the lipid membrane and they have their target receptor on the cell membrane. the receptor are fixed on the cell membrane, so. Mechanism of hormone action: hormones produce their effects on target tissues by binding to receptor proteins present in the target tissues. on the basis of chemical nature, hormones are divided into: peptide, polypeptide & protein hormones: insulin, glucagon, pituitary hormones, hypothalamic hormones.

Mechanism. 2. mobile receptor mechanism. the hormones which can easily pass through the lipid membranes or are lipid soluble are mainly involved in this type of mechanism. hormones like fatty acids or other types of steroid hormones are known for easily moving across the plasma membrane and therefore, they possess intracellular receptors. Secondary messengers for lipophobic hormones that cannot pass the cellular membrane, activity is mediated and amplified within a cell by the action of second messenger mechanisms (molecules that relay signals from receptors on the cell surface to target molecules inside the cell in the cytoplasm or nucleus). Steroid hormones. longer half lives. primary effects are slow in onset (due to action through nuclear mechanisms) and slow to subside. receptor characteristics. macromolecules. binding affinity is proportional to the potency of the hormonal ligand. binding is saturable. binding is high affinity. binding is stereospecific.
