According to the research, the correct option is gap junctions. Protein channels that are situated between cells create small pores for the passage of small substances are known as gap junctions.

What are gap junctions?

They are molecular complexes made up of connexins as channels or connection structures between cells that allow the passage of small molecules and electric current.

In this sense, these channel structures formed by proteins allow the adaptive responses of differentiated cells and the synchronization of cell function, the transmission of the electrical impulse, among many other biological activities.

Therefore, we can conclude that according to the research, the correct option is gap junctions. Protein channels that are situated between cells create small pores for the passage of small substances are known as gap junctions.
