WebSep 7, 2024 · Each enzyme has a highly specific geometric shape that is complementary to its substrate. In order to activate an enzyme, its substrate must first bind to the active site on the enzyme. Only then will a catalytic reaction take place. However, like a lock and a key, the enzyme and substrate shape must be complementary and fit perfectly. WebEnzymes react with another molecule called a substrate .Each enzyme has its own special shape with an area called the active site (specific), onto which the substrate molecules bind . This creates an enzyme-substrate complex.
