Question

Every receptor has a unique ligand and every ligand works through a unique and specific receptor. True or False, explain with examples.

Answer 1

The statement is True

Receptors and ligands come in many forms but they all have one thing in common; they come in closely matched pairs with a receptor recognizing just one specific ligands and a ligand binding to just one target receptors. Binding of a ligand to a receptor changes its shape or acivity, allowing it to transmit a signal or directly produce a change inside of the cell.

For example, the primary receptors for hydrophobic steroid hormones, such as the sex hormones estradiol and testosterone are intracellular.
