Pan-African flag - History. 1  The flag was created in 1920 by members of UNIA in response to the enormously popular 1900 coon song Every Race Has a Flag but the Coon. [4] which has been cited as one of the three songs that firmly established the term coon in the American vocabulary.
Whether a hormone binds to a receptor inside or outside a cell depends on the chemical nature of the hormone and its compatibility with the cellâs fatty outer membrane. The membraneâs fat layers impede water-friendly hormones from passing through but allow fat-derived hormones to readily enter the cell.
Genomic mechanisms [edit]. Mineralocorticoids bind to the mineralocorticoid receptor in the cell cytosol, and are able to freely cross the lipid bilayer of the cell. This type of receptor becomes activated upon ligand binding.
