What is the difference between a ligand and a receptor? Give an example.

Solution

Answer:

A ligand is a biological molecule that binds to another molecule.Ex. Hormones and neurotransmitters.

A receptor is a protein to which a signalling molecule (such as a neurotransmitter, drug, or hormone) binds specifically and stimulates a particular response by a cell.

Ex.

A hormone binding to a receptor.

Oxygen binding (ligand) to haemoglobin (receptor).

Antibodies (ligand) binding to antigens (receptor).
