Question

A water-soluble hormone binds to its receptor on the plasma membrane. Arrange the events that follow in correct sequence. (1) alpha subunit-GTP complex alters cell activity (2) GTP binds to the alpha subunit replacing GDP (3) G-protein subunits separate from the receptor (4) alpha subunit separates from other two subunits (5) G-protein subunits bind to the receptor

Answer 1

Answer:

G-protein subunits bind to the receptor

GTP binds to the alpha subunit replacing GDP

G-protein subunits separate from the receptor
