NEET Zoology Synaptic Transmission Assertion Reason Question
Assertion (A): Chemical synapses are slower in impulse transmission compared to electrical synapses. | Reason (R): In chemical synapses, neurotransmitters have to diffuse across the synaptic cleft and bind to receptors on the post-synaptic membrane.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
