Question

lets recap what you have just learned: which of these statements is correct for an electrical synapse? a) electrical synapses mean that there is a synaptic cleft between the presynaptic and postsynaptic cells b) electrical synapses allow the flow of ions both ways between presynaptic and postsynaptic cells c) electrical synapses are versatile as they can conduct both excitatory and inhibitory signals d) electrical synapses are dependent on neurotransmitters traveling from presynaptic to the postsynaptic cell

Explanation:

• Option a: Electrical synapses have gap junctions, not a synaptic cleft. Chemical synapses have a synaptic cleft.
• Option b: Electrical synapses allow bidirectional ion flow through gap - junction channels.
• Option c: Chemical synapses are more versatile for conducting excitatory and inhibitory signals. Electrical synapses mainly conduct signals in a more straightforward, less modifiable way.
• Option d: Chemical synapses are dependent on neurotransmitters. Electrical synapses rely on ion flow through gap junctions.

Answer:

B. Electrical synapses allow the flow of ions both ways between presynaptic and postsynaptic cells
