Question

Tight junctions are particularly important in epitheliale the lining of the small intestine Why? A Without light junctions, it would not be possible for coils to communicate quickly with adjacent cells by sending small molecules through these connections in the cytoplasm B Without tight junctions, bulk transport of oxygen would not be possible C Without tight junctions, it would not be possible to maintain the gradient for nutrients like glucose and amino acids that allow them to be absorbed into the circulatory system D Without light junctions, the cells would not adhere to one another and the sheets of cells would come apart

Answer 1

Ans-the function of the tight junction to limiting the movement of solute and water through space between plasma membranes of adjacent cells and also helps to maintain cell polarity. tight junction act as a selective barrier across epithelial cells sheet.

so option C without tight junction, it would not possible to maintain the gradient for the nutrients like glucose amino acids that allow them to absorb into the circulatory system is the correct option
