Enzyme Investigation An enzyme was isolated from digestive juices taken from the small intestine. An experiment was set up to test the ability of the enzyme to break down protein. Two test tubes, labeled A and B, were placed in a hot water bath at 37°C, human body temperature. Test tube A contained only protein and test tube B contained protein and the enzyme. The chart below shows the set-up. Test Tube Contents A protein В protein, enzyme After two hours, the contents of both test tubes were analyzed. Test tube A showed only the presence of protein. Test tube B showed the presence of the end products of protein digestion, indicating the enzyme had successfully broken down the protein. 17. Explain the importance of temperature in the functioning of enzymes. 18. Identify the end products of protein digestion that made up the contents of test tube B after the two hours. 19. In the digestive system many large molecules, such as proteins, are broken down into much smaller molecules. State what happens to these smaller molecules following digestion.

An enzyme was isolated from digestive juices taken from the small intestine. An experiment
was set up to test the ability of the enzyme to break down protein. Two test tubes, labeled A and B,
were placed in a hot water bath at 37°C, human body temperature.
Test tube A contained only protein and test tube B contained protein and the enzyme. The chart
below shows the set-up.

В
protein, enzyme
After two hours, the contents of both test tubes were analyzed. Test tubeA showed only the
presence of protein. Test tube B showed the presence of the end products of protein digestion,
indicating the enzyme had successfully broken down the protein.
17. Explain the importance of temperature in the functioning of enzymes.
18. Identify the end products of protein digestion that made up the contents of test tube B after the
two hours.
19. In the digestive system many large molecules, such as proteins, are broken down into much
smaller molecules. State what happens to these smaller molecules following digestion.
