Pleas help me Its for a test Base your answer on the information below and on your knowledge of biology. 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. 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. Identify the end products of protein digestion that made up the contents of test tube B after the two hours.
