What is osmosis? describe this process including the types of molecules that move and the energy required. include in your description details about the areas of concentration on either side of a membrane when osmosis occurs.

Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane. Any solvent can undergo the process of osmosis including gases and supercritical liquids.

Explanation:

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
