5. Six test tubes were set up at different temperatures. Each contained identical solutions containing starch and amylase mixtures. The table shows the time taken for the reactions to finish in each test Temperature/°C Time/s 15 25 35 45 55 65 35 22 13 5 35 66 At which temperature does the amylase work best? A 15 °C B 35 °C C 45 °C D 65 °C Interpretive questions 1. Study the diagram below and answer the questions that follow. A B F Figure 3.13 a) Which of the substrates (A, B or C) will fit into the active site of the enzyme? b) Draw the enzyme-substrate complex formed between the enzyme and the correct substrate. Label the active site. ) Explain how your diagram shows why enzymes are specific. If the enzyme was heated to 75 °C would is 11​
