Enzymes: A Study Guide

Enzymes Worksheet 1. What type of macromolecule are enzymes?: Proteins 2. What are enzymes?: proteins that act as biological catalysts 3. What are catalysts?: A substance that increases the rate of chemical reaction 4. Label the following picture: On sheet 5. What do enzymes do to the activation energy?: Slow down 6. What do enzymes do in chemical reactions?: Enzymes speed up the reaction by lowering the activation energy 7. Enzymes - Enzyme-Substrate Complex: Enzymes provide a site where reactants can be brought together to react 8. Enzyme - Product: the energy needed for reaction 9.
