84.Given that most ligands form covalent bonds with their associated receptors, these complexes are more or less permanent and can only be broken through the hydrolysis of ATP. A) True B) False
85.A researcher has discovered a new ligand that can pass through the cell membrane and bind to a receptor in the nucleus. Which of the following statements is FALSE regarding this ligand?

87.A researcher is studying a G protein–coupled receptor in eukaryotic cells. In one group of cells, he notices that even though a ligand can bind to its G protein–coupled receptor, nothing happens. Why could this happen?
88.A bacterium releases a toxin that binds to and activates a G protein-coupled receptor in the mammalian gut. The result is high levels of cAMP in these cells. This toxin might work by: A) binding to and activating the G protein–coupled receptor in these cells.
