Describe three specific reasons why a change in cell volume can be problematic
What will be an ideal response?
Answer: Cells can maintain volume by actively creating concentration gradients on either side of the membrane that induces the movement of water into or out of the cell. Changes in cell volume are problematic for a variety of reasons. Severely hypotonic conditions can cause a cell to explode, triggering a local immune response that can disrupt neighboring cells. Also, swollen cells can disrupt tissue structure or occlude blood vessels. When water movement changes cell volume, it also affects the intracellular concentration of metabolites and enzymes within cells, disrupting metabolic regulation. Finally, changes in cell volume can deform the cytoskeleton and plasma membrane, altering the function of receptors and transporters.
