Final answer:
True, Connexons are critical components of electrical synapses as they form gap junctions that allow for the direct passage of ions and fast signal transmission between cells.
Step-by-step explanation:
Connexons are indeed a necessary component of electrical synapses. This is because an electrical synapse is a type of connection between two neurons, or any two electrically active cells, where ions flow directly through channels spanning their adjacent cell membranes.
These channels are formed by proteins called connexins, which come together to form connexons and create gap junctions. These gap junctions allow for the direct passage of ions and other small molecules such as ATP, enabling rapid signal transmission and synchronization of activity between cells.
