DownloadWhat is a hormone?
Flip card
A hormone is a chemical secreted by a cell or group of cells into the blood for transport to a distant target, where it is effective at very low concentrations.
What are the three basic ways in which hormones act on their target cells?
Flip card
Hormones can control the rates of enzymatic reactions, control the transport of ions or molecules across cell membranes, or control gene expression and protein synthesis.
How do hormones bind to target cells?
Flip card
Hormones bind to target cell receptors and initiate biochemical responses.
What are the three main chemical classes of hormones?
Flip card
The three main chemical classes of hormones are peptide/protein hormones, steroid hormones, and amino acid-derived (amine) hormones.
How are peptide hormones synthesized, stored, released, and transported?
Flip card
Peptide hormones are synthesized as preprohormones on ribosomes, converted to prohormones in the ER, processed in the Golgi complex, and released into the extracellular space through secretory vesicles. They are then transported in the bloodstream to their target cells.
How do peptide hormones act on target cells?
Flip card
Peptide hormones are lipophobic and bind to surface membrane receptors on target cells. They initiate a cellular response through a signal transduction system.
Give an example of a peptide hormone.
Flip card
Insulin is an example of a peptide hormone.
Where are steroid hormones derived from?
Flip card
