SECTION 2.4: ENZYMES

Discover the role of enzymes as biological catalysts, how they lower energy of activation, speed up reactions, and their specificity due to unique shapes. Learn how enzymes can be damaged and denatured by factors like pH, salt concentration, and heat.

Presentation Transcript

  1. SECTION 2.4: ENZYMES

  2. WHAT ARE ENZYMES? • Biological catalysts • Proteins! • Very large!!!

  3. Enzymes lower the energy needed for a chemical reaction to occur • ENERGY OF ACTIVATION!!!!

  4. Enzymes speed up chemical reactions

  5. HOW DO ENZYMES WORK? • Each enzyme catalyzes only ONE chemical reaction • Enzymes are SPECIFIC • A particular enzyme can only speed up its own unique reaction • Why? Enzymes have a unique shape

  6. Because enzymes are proteins, they can be damaged (denatured) by changes in: • pH • Salt concentration • Heat
