• movement of molecules and ions

• down a concentration gradient

• from a high concentration to a low concentration

• movement of water molecules

• Requires membrane proteins

Why is enzyme substrate specificity crucial for their function?

• It allows enzymes to work on a wide range of substrates

• It ensures that enzymes only work on specific substrates

• It has no impact on the function of enzymes

• It makes enzymes less effective
