In Insects Such as Drosophila Melanogaster, Electrical Synapses Are Abundant

Multiple Choice

In insects such as Drosophila melanogaster, electrical synapses are abundant in the ventral nerve cord. Unlike a chemical synapse, the cytosols of pre- and postsynaptic cells in an electrical synapse are connected, allowing action potentials to spread rapidly and without delay. What junctional proteins in the flies are chiefly responsible for this unique feature of the electrical synapses?

A) Cadherins
B) Claudins
C) Connexins
D) Innexins
E) Integrins
