1.Enzymes work best at optimum temperatures and pH. ▫extreme temperature and pH can change the shape of the enzyme, affecting the binding “active” site. ▫Conditions too far away from the ideal may cause the enzyme to denature and not work. ▫Enzymes in our body work best at 37 C (98.6 F) and at pH between 6.5 and 7.5. Acid = 0-6.9 Neutral = 7 Base = 7.1 - 14
2. Are specific for what they will catalyze (only work for one type of reaction) A. B. C. Which substrate fits with the enzyme? enzyme
3. Are reusable (finish a reaction exactly like they began it).
Enzymes are classified as which of the following biological organic compounds? A.Carbohydrates B.Lipids C.Nucleic acids D.Proteins
Bellringer 3/5 How does an enzyme affect the activation energy of a chemical reaction? How does that affect the rate of the chemical reaction? What two factors affect the activity of an enzyme?
