Covalent bonds is important in four macromolecules such as proteins (polymers of amino
acids), nucleic acids (polymers of nucleotides), carbohydrates (polymers of
sugars) and lipids (with a variety of modular constituents) because they served
as a basic structure of macromolecules.
In addition, the resulting covalent bond is a result
of sharing a pair of electrons, one from each atom or molecular units.
Answer:
Tight junctions are specialized regions of the plasma membrane that mediate separation of the apical and basolateral membranes.
Explanation:
Transcellular Transport is the pathway in intestinal epithelial cells where particles move from one cell to another depending on the physicochemical properties of the particles passing both the the apical membrane and basolateral membrane. Tight junctions create a paracellular barrier in epithelial and endothelial cells protecting them from the external environment
