Enzymes State what an enzyme is and what
- Slides: 5
Enzymes * ** *** State what an enzyme is and what it is made of Describe the conditions under which enzymes work best – or stop working Explain why enzymes work best under these conditions (lock and key theory)
What are enzymes? • What are enzymes made of? Enzymes are made of protein. Each enzyme is different as they are a specific shape for the reaction they are involved in • What are they for? Enzymes speed up a reaction. • Are they limited in how they work? How can we find out? * ** *** State what an enzyme is and what it is made of Describe the conditions under which enzymes work best – or stop working Explain why enzymes work best under these conditions (lock and key theory)
Effect of temperature on enzyme activity Potato or celery extract Heat one only Add hydrogen peroxide to both Observe Record your findings in your book * ** *** State what an enzyme is and what it is made of Describe the conditions under which enzymes work best – or stop working Explain why enzymes work best under these conditions (lock and key theory)

How enzymes work What happens when the enzyme gets too hot? (Hint: The word we use is denatured) What is the ideal temperature for enzymes to work at? Is temperature the only factor to affects how well an enzyme works? Make notes in your book explaining what you have found out today * ** *** State what an enzyme is and what it is made of Describe the conditions under which enzymes work best – or stop working Explain why enzymes work best under these conditions (lock and key theory)
