Question

Assertion:
Receptors are crucial to the body's communication process.
Reason:
Receptors are proteins.
A.Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
B.Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
C.Assertion is correct but Reason is incorrect
D.Both Assertion and Reason are incorrect

Answer 1

Hint: Receptors are those proteins which help in the process of communication but they cannot solely exert the communication process. Neurotransmitters are required to send the signal to the cells which is a crucial part of the communication process.

Complete answer:
Receptors are proteins which receive and transduce signals in bodily functions. Receptors cannot work alone to receive and transmit signals to the brain and take signals from the brain. Neurotransmitters are equally important in any communication process as it works in transmitting the signals from the brain to the receptors.
Receptors are of various types which conduct different bodily functions. Without receptors the communication process cannot occur as cells will not be able to receive the signal sent by the brain. Thus, the assertion is correct. The receptors are proteins, thus the reason is also correct.
But, the reason that receptors are proteins is not the correct explanation for receptors being crucial to the communication process.
Thus, option B is the correct option.

Note:
As much as receptors, neurotransmitters are also important for the communication process. Neurotransmitters are made up of neurons and they also communicate through neurons. Receptors and neurotransmitters depend on each other and without one, the other cannot pass the signal and the communication process cannot occur.
