Why are water and electrolytes transported in both directions through tight junctions and intercellular spaces rather than across cell membranes?
A) Because the intercellular hydrostatic pressure is inadequate to push the water and electrolytes across the cell membranes
B) Because a balance of cations and ions among the electrolytes on each side of the cell membranes cannot be maintained
C) Because the epithelial cell membranes are formed of lipids that are hydrophobic and,thus,repel water
D) Because receptors on those cell membranes are occupied with a diffusion of amino acids and monosaccharides

Question

Quizplus · Accepted Answer

The epithelial cell membranes are composed of lipid bilayers that are hydrophobic, making it difficult for water and electrolytes to pass directly through them. Instead, these substances move through tight junctions and intercellular spaces.
