Enzymes

Question 1

Explain what enzymes are in 5 bullet points

Answer 1

• enzymes are biological catalysts
• Catalysts increase the rate of chemical reactions (but not used up in the reaction)
• Enzymes are proteins made of amino acid chains
• The chains are folded to form the active site
• The active site is where the substrate of the reaction blinds with the enzyme

Question 2

What factors affect enzyme action?

Answer 2

• Enzymes have an optimal temperature and pH to work at.
• High temperatures and the wrong pH can change the shape of the activities site to stop an enzyme working
• the change in shape is called denaturing
