  • B2.12 enzymes

    1. 1. Starter: List three things you know about enzymes. Enzymes
    2. 2. Enzymes WALT: To be able to describe the role of enzymes. WILF: ~ Recall that enzymes are a protein. (D) ~ Describe how enzymes catalyse reactions without being used up themselves. (C) ~ Describe the role of particular examples of enzymes both inside and outside cells. (B) ~ Explain the importance of enzymes and how they are specific to different reactions. (A/A*) Keywords enzyme digestion catalyst
    3. 3. What are enzymes? Enzymes are proteins. They help to carry out chemical reactions in the body. They are catalysts. They are specific. Globular shaped protein
    4. 4. What are enzymes? What is the function of enzymes? Describe what the word catalyst means. Explain why enzymes are specific. Globular shaped protein
    5. 5. Enzymes inside cells Enzymes outside cells
    6. 6. Microorganisms and fungi also use digestive enzymes to digest foodsaprophytic feeding.
    7. 7. Enzymes and dirty socks! Biological detergents contain enzymes. These enzymes catalyse the breakdown of some of the substances found in stains on dirty clothes. You are going to compare the cleaning power of a biological detergent with a non-biological detergent, to see what effect the enzymes have.
