Catalysts lower the Activation energy for reactions. The lower the activation energy for a reaction,the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrate ms bind.
The<u> ion concentration</u> in water molecules controls the amount of water in a compartment
The concentration of ions in a body of water determines the rate of diffusion and osmosis that occurs in a body of water contained within a body compartment. which has a direct impact on the amount of water that is held in any water body compartment.
Hence we can conclude that the ion concentration in water molecules controls the amount of water in a compartment.
