Assertion: Receptors are crucial to body’s communication process.
Reason: Receptors are proteins.
Assertion
⮚ Receptors interact with several types of chemical messengers & they are selective & specific in their interaction with the chemical messengers.
⮚ It is mainly due to their structural properties which allow the chemical messengers to bind to their binding sites and carry the message to the cell. They sometimes
carry coded genetic information for the cell, so receptors are crucial to body’s communication process.
So, assertion is correct.
Reason
⮚ Receptors are actually proteins & their binding sites have different shapes, structures, & amino acid compositions.
Hence, assertion and reason both are correct statements, but reason does not explain assertion.
So correct answer is option (A).
