Answer:
Receptors are highly specific and only have high affinity for those ligands for whom they are specific.
Explanation:
Receptors are proteins that receive a stimulus or bind a ligand and mediate effects via receptor effector system.
Receptors are macromolecules that are highly specific.
The affinity between the ligand and the receptors is determind by the disassociation constant Kd.
The receptors produce maximun effect when an appropriate specific stimulus is present.
Different recptors types are present for different ligands.
For example, muscrinic receptors are specific for acetycholine and adrenergic receptors are specific for adrenaline/nor adrenaline.
It is important to know the specificity so that the body remains in a state of balance.

Explanation:
Chalcone synthase is an enzyme ubiquitous to higher plants and belong to the family of polyketide synthase enzyme known as type lll PKS. Type lll PKS are associated with the production of chalcones, a class of organic compounds found manly in plants as natural defense mechanisms and as synthetic intermediates CHS was the first type lll PKS to be discovered. it is the first committed enzyme in flavenoid biosynthesis. the enzyme catalyze the conversion of malonyl-coA to narigenin chalcone.
