Table showing how long it took amylase to break down starch after being treated at different temperatures

Use the results to plot a hand drawn graph. Write a report based on the results and your understanding of enzyme structure and function n. (1.1, 1.2, 2.1, 2.2, 2.3, 2.4) (Maximum 700 words)

In your report include the following points and relate your answers to the results of the practical.

• What were the effects of temperature on the enzyme amylase structure and function? Discuss the effect on the different levels of protein structure in your answer. (1.2, 2.1).
• Briefly explain how an enzyme affects the activation energy of a reaction. (2.2)
• Explain how 2 other factors (i.e. other than temperature) could also interfere with the enzyme's ability to break down starch. (2.4)
• Amylase works via the induced fit model of action (Thome and Koshland, 1960). Briefly explain this model and compare it to the lock and key model. (2.3)
