Q6 (AC 3.1) [A] The diagrams below show two possible models to explain how enzymes catalyse chemical reactions in biological systems. State the name of each model in the space provided Model A product ative se Name of model A: :(write your answer here) Name of model B: :(write your answer here) Substrate entering the active site of Enzyme/substrate complex Enzyme/product complex Products leaving the active site of the enzyme the enzyme Use your knowledge gained during the biology sessions and from the diagrams previous, to choose appropriate statements from the list below to complete the table to contrast the two models of enzyme action. You must use each statement only ONCE: Lock and key model Induced fit model Feature Description of (write your answer here) the model Shapes of :(write your answer here) molecules Nature of :(write your answer here) bonding within the E-S complex Who proposed (write your answer here) each theory/model? Active site (write your answer here) behaviour Year :(write your answer here) discovered Specificity of :(write your answer here) enzyme for substrate enzyme enzyme substrate entering active site Model B enzyme/substrate complex Substrate Active site ↑ enzyme/product complex Enzyme changes shape slightly as substrate binds ↑ enzyme + product leaving active site Products ↑ ↑
