A step that is not part of transepithelial transport would be the movement of a substance
A)through the cytosol of the tubular cell
B)across the glomerular capillary wall
C)across the luminal membrane of the tubular cell
D)through the interstitial fluid
E)across the basolateral membrane of the tubular cell

Question

Quizplus · Accepted Answer

Transepithelial transport specifically refers to the movement of substances across both the apical (luminal) and basolateral membranes of the epithelial cells lining a tubular structure in the body (e.g. renal tubule, small intestine). Therefore, movement across the glomerular capillary wall, which does not involve the epithelial cells, is not considered transepithelial transport. The other choices all involve movement of substances across the epithelial cells and are part of transepithelial transport.
