The Enzyme Quiz

• Principle 2: Enzymes lower activation barriers selectively
• Principle 3: Enzymatic reactions occur in specialization pockets called active sites (correct)
• Principle 4: Enzymes bind most tightly to the transition state of the catalyzed reaction
• Principle 1: Enzymes are powerful biological catalysts

• Enzymes increase the specificity of reactions
• Enzymes increase the activation energy of reactions
• Enzymes decrease the activation energy of reactions (correct)
• Enzymes decrease the rate of reactions

• Enzymes do not require activation energy
• Enzymes do not affect the reaction rates
• Enzymes do not occur in specialization pockets
• Enzymes exhibit a high degree of specificity (correct)
