Read the following statements and choose the following option: 1....
Read the following statements and choose the following option:
1. Synaptic cleft conjoins the pre and post-synaptic neurons
2. Electrical synapse is faster than chemical synapse
3. Sodium potassium pump transports 2 sodium ions outwards
4. A rapid influx of Na⁺ leads to the reversal of the polarity at that site, i.e., the outer surface of the membrane becomes negatively charged and
the inner side becomes positively charged.

Options
- AOnly 1 is correct
- BAll are incorrect
- COnly 2 and 4 are correct
- DBoth 1 and 3 is correct
Correct answer
C. Only 2 and 4 are correct
Step-by-step solution
Transmission of an impulse across electrical synapses is very similar to impulse conduction along a single axon. Impulse transmission across an electrical synapse is always faster than that across a chemical synapse.
