Question

1.Which of the following is true about synapses:

1. Chemical synapses and electrical synapses are two types of connections between electrically active cells (meaning that the cell can generate an electrical impulse/action potential).
2. In an electrical synapse, a neurotransmitter is released from one cell and it affects the other cell
3. In an electrical synapse, there is a direct connection between the two cells so that ions can pass directly from one cell to the next.
4. A and C
5. All of the above

Answer 1

The correct answer for the question is option d .

Reason : Statement a is correct as chemical and electrical synapses are the two types of syapses that helps in the connection between electrically active cells like neurons .

Option C is also correct as in electrical synapse there is a direct connection between the two cells mainly through structures called Gap junctions which is responsible for allowing the ions to pass from one cell to another directly through them, and thus helps in the propagation of action potential through the passage of these ions.

Option b is wrong as no neurotransmitters are involved in electrical synapses.

Hence as both statement a and c is correct so the option d becomes the required answer for this question.
