Presumably, hyperglycemia promotes cellular dehydration because: glucose, as an energy source, accelerates the osmotic work performed by plasma membranes. glucose, as an energy source, accelerates plasma membrane ion exchange pumps. glucose molecules raise the osmotic pressure of the extracellular space. glucose molecules are exchanged for water molecules across the plasma membrane.

The answer is C.

Explanation:

Hyperglycemia is a condition where the body does not produce enough insulin for different reasons and this results in excess amounts of sugar in the bloodstream.

Hyperglycemia can cause cellular dehydration because glucose is causes the glucose molecules to build up in the bloodstream of the body, increasing it's concentration, which in turn causes a density difference of glucose between the two environments, the inside of the cells and the extracellular space, thus resulting in an increased osmotic pressure.

I hope this answer helps.
