Endocrine glands
|
Body structures specialized for secretion
|

(MHC) these protiens can change in their molecular structure- from type IIx to IIa heavy-chain proteins

|
Lock-and-key theory
|
When a given hormone interacts with a specific recptor, principle of endocrinology

|
Cross-reactivity
|
A given receptor partially interacts with hormones that are not specifically designed for it

|
Allosteric binding sites
|
Substances other than hormones can enhance or reduce the cellular responto the primary hormones
|
|
Downregulation
|
When adaptation is no longer possible (when the maximal amount of protein has been added to the muscle fiber) receptors can become nonresponsive to a specific hormone, preventing it from stimulating the protien synthesis response in the cell
