The presence of a synaptic cleft between cells is characteristic of:
A)electrical synapse.
B)chemical synapse.
C)both chemical and electrical synapses.
D)neither chemical nor electrical synapses.

Question

Quizplus · Accepted Answer

A synaptic cleft is the space between two neurons at a chemical synapse, where neurotransmitters are released from the presynaptic neuron to bind to receptors on the postsynaptic neuron. Electrical synapses, on the other hand, have no synaptic cleft and instead have direct electrical connections between neurons. Therefore, the presence of a synaptic cleft is characteristic of chemical synapses, making option B the correct choice.
