Problem 13: Cell junctions

Correct!

The cell junctions respectively that exclude the passage of water between cells, maintain tissue form and strength, and allow the exchange of small molecules between cells are:

A. gap junctions, desmosomes, and tight junctions.
B. desmosomes, tight junctions and gap junctions.
C. tight junctions, gap junctions, and tight junctions.
D. gap junctions, tight junctions, and desmosomes.
E.

tight junctions, desmosomes, and gap junctions.

Yes, and note that the component of the cell membrane responsible for the functions of desmosomes, tight junctions, and gap junctions are proteins.
