Q. No.Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
| Assertion (A): | Electrical synapses are faster but rare in human beings. |
| Reason (R): | Electrical synapses contain gap junctions that allow electric current to flow directly from one neuron to another. |
In the light of the above statements choose the correct answer from the options given below:
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
Subtopic: Â Synapse |
Level 3: 35%-60%

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
| Assertion (A): | Most of the synapses in vertebrates conduct information in only one direction. |
| Reason (R): | Only the postsynaptic cells can bind and respond to neurotransmitters. |
In the light of the above statements choose the correct answer from the options given below:
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | Both (A) and (R) are false. |

Hints
Consider the two statements:
I. Electrical synapses are rare in our system.
II. Electrical synapses conduct impulse faster than the chemical synapse.
1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. Only I is correct
4. Both I and II are incorrect
