Give the importance of the lock and key model of an enzyme

The lock and key model only allows one type of specific substrate to form a substrate-activesite complex with each specific type of enzyme. This is due to their complementary shapes, as only one shape and hence one type of substrate can fit into an enzyme's active site.Therefore each biological reaction requires different enzymes to act as biological catalysts.
