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 c

Options

  1. AOnly 1 is correct
  2. BAll are incorrect
  3. COnly 2 and 4 are correct
  4. 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.
