Section Assignment 2.3 Part A Enzyme Matching Write the letter of the term beside its correct definition. Term Definition A Vitamins 1. All of the chemical reactions that occur in a cell. B Induced fit model 2. Non-protein molecules required for enzymes to function correctly. C Competitive inhibitor 3. An essential component of an organism's diet; often form part of coenzymes. D Denatured 4. An enzyme's active site is altered by damage; its substrate can no longer bind to it. E Reaction rate 5. Reactant(s) in a biochemical reaction catalyzed by enzymes. F Cofactors 6. Explanation stating that an enzyme slightly changes its shape in order to better fit with its specific substrate G Substrate 7. The speed at which reactants are converted to product(s) in a chemical reaction H Metabolism 8. A molecule that binds to an enzyme at a site other than the active site; causes the enzyme to change shape, the active site is altered and the enzyme cannot bond with its substrate. Non-competitive 9. In a reaction pathway, product inhibitor molecules halt the production of any more product
