The answer is B: A molecule that can occupy a receptor site while not activating the receptor. A ligand is a molecule that, in some situations, binds a signal to a particular molecule. Therefore ligands can be seen as molecules of signals. Ligands interact with proteins that influence chemical signals in target cells; these proteins are also termed receptors.

A Lingard is a mole that can occupy a receptor site while not activating the receptor. It irreversibly bores to a receipt molecule of protein which is also termed as the receptor. The alteration of the shape and the activity of the ligand after the binding of the receptors that are respective after the initiation of the various modes of responses from the cellular.

"A-Any small molecule that can bind in a specific manner to a larger one." A ligand refers to a molecule that attaches to another molecule and, in some situations, transmits a signal due to the binding. As a result, ligands can be considered signaling molecules. Ligands bind to proteins on target cells or cells that respond to chemical signals. Receptors are another name for these proteins.
