When there are different amounts of a substance on either side of the cell membrane (a)?
This depends if the particular cell membrane is permeable to the substance or not. If so, then if there was a larger amount of the substance on the outside, it would diffuse into the cell down the concentration gradient. For it to go the other way would require ATP used in active transport.
What is another word for Substance that dissolves in water?
