1.	Which of the following is defined by the tight junctions?(a) Efficiency of drugs(b) Diffusion of drugs(c) Breakdown of drugs(d) Absorption of drugsThe question was posed to me by my college director while I was bunking the class.My doubt is from Extracellular Matrix and Cell Interactions in section Extracellular Matrix and Cell Interactions of Cell Biology
Answer» Correct option is (b) Diffusion of drugs The best I can explain: The TIGHT junctions take CARE of the permeability of the molecules through the CELLS. THUS the tight junction is RESPONSIBLE for the diffusion of the drugs through the cells.
