Presentation transcript:

Use the videos and the notes you have to answer the questions What are Enzymes? An introduction to enzymes. This should also help you with digestion revision. Use the videos and the notes you have to answer the questions

The starter video What mechanical digestion is mentioned? What do enzymes do to chemical reactions? Which two digestive enzymes are mentioned? Which is the most important part of an enzyme? What word describes each enzyme binding to only one substrate? Why can’t glucose be broken down by lipase? Why is only a small amount of enzyme needed to speed up thousands of reactions?

The Activation Energy video Watch the video. Then draw a graph showing the activation energies with and without an enzyme present.

Model of enzyme action video Draw the before/during/after diagrams for the ‘lock and key’ model of enzyme action. Use as many key words as possible Explain what is different in the ‘induced fit’ model

Well done!
