The increasing order of permeability would be: calcium, glucose, ethanol, water.

Explanation:

This increasing order is due to the fact that calcium does or does not need an ATP-dependent pump, which is a not only selective passage, but ATP-dependent, glucose if or if it needs one of the most important hormones in the body, which is insulin. and it is released by the pancreas and not only that, but 80% of the cells have insulin receptors.

Then ethanol continues, since being an alcohol the diffusion through the biological cell membranes is high, that is why it is considered so toxic and harmful. And finally water, the body is made up of 80% water, which means that almost all cells have aquaporins or are highly permeable to water to meet the body's physiological balance through the process of osmosis.
