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.
1. A ligand is... a small molecule that binds to the alpha subunit of the G-protein. a small molecule that binds to a membrane-bound receptor. a large molecule that binds to the alpha subunit of the G-protein.a large molecule that binds to a membrane-bound receptor.s a result of the ligand binding to its site... the G-protein changes conformation and GTP replaces the GDP on the alpha subunit. the G-protein changes conformation and the alpha subunit separates from the beta and gamma subunits. the G-protein changes conformation and GDP replaces the GTP on the alpha subunit.
