Note: In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.
Assertion : Chemical messengers are chemicals that enable communication of message between two neurons or between neurons and muscles
Reason : Chemicals enter the cell through receptor.
• Chemical messengers are chemical substances which process the communication between 2 neurons and b/w neurons & muscles .
• These Chemical messengers are received by the receptors through bonding to the binding sites of the receptors proteins.
• To put up messengers, shape of a receptor site changes to transfer the message into cells.
• Thus the Chemical messengers transfer messages into cells without even entering the cell but it cannot explain the communication b/w cells and therefore the given assertion.
