A Particular Epithelium Has a Paracellular (Between the Cells) Pathway

question 36

Multiple Choice

A particular epithelium has a paracellular (between the cells) pathway permeable to water and chloride. In order to enhance the net movement of NaCl and water from apical to basolateral portions of the cell, the epithelium needs:

• A) Basolateral Na⁺K⁺-ATPase, basolateral K⁺ channels, and apical Na⁺ channels
• B) Apical Na⁺K⁺-ATPase, apical K⁺ channels, and basolateral Na⁺ channels
• C) Basolateral Na⁺K⁺-ATPase, apical K⁺ channels, and basolateral Na⁺ channels
• D) Apical Na⁺K⁺-ATPase, basolateral K⁺ channels, and apical Na⁺ channels
• E) Basolateral Na⁺K⁺-ATPase, basolateral K⁺ channels, and basolateral Na⁺ channels
