Lesson 8: The Role of EnzymesFocus on InquiryScientists often make inferences. Recall that an inference is based on observations and previousknowledge. An inference is not data, but it should be consistent with the data.Recall that pH can affect the function of enzymes. A scientist was studying the digestive system ofalligators. Alligators have very acidic stomachs, but their intestines are closer to neutral. The scientistidentified two important enzymes in the digestive tract of alligators W-protease and T-protease.She conducted an investigation into how a change in pH affected the activity of each enzyme. At theconclusion of the investigation, she presented her findings in the line graph shown....Digestive Enzyme ActivityTan-protease--- Wx-protease461012pHBased on these data and your knowledge of enzymes, what inferences can you draw about whichenzyme is most likely to be active in the alligator intestine and which is most likely to be activein the stomach?

The catalytic activity of enzymes depends on the presence of appropriate environmental conditions. Pepsin is a digestive enzyme found in the stomach and facilitates the digestion of large proteins. If pepsin is removed from this acidic environment of the stomach and is instead placed in a more basic environment, it will cease to function. Describe the specific effect that a change in environmental pH will have on pepsin and explain how this change can lead to inhibition of its catalytic activity. Respond in 4 to 6 complete sentences.
Both the esophagus and the small intestine are involved in the digestion of food. The esophagus squeezes food into the stomach by wave-like muscle contractions. Peptidase enzymes in the small intestine break food molecules into smaller molecules. Which statement best describes changes to food during digestion? O The muscle contractions result in physical changes, while the action of the peptidase results in chemical changes. O The muscle contractions and the action of the peptidase both result only in physical changes. O The muscle contractions result in chemical changes, while the action of the peptidase results in physical changes.

Introduction to Experiment 2: Protein Digestion by Pepsin In this experiment, we will look at for evidence of protein digestion using albumin, a protein, and Biuret reagent. Biuret reagent is used to test for the presence of proteins, or more specifically, peptide bonds. When long polypeptide chains are present the solution will turn violet, and when shorter polypeptide chains are present the solution will turn a lighter pink color. What is/are the end product(s) of protein digestion? Amino acids What is the purpose of the enzyme pepsin? It helps in the digestion of proteins by breaking down the peptide bonds between amino acids into smaller peptides If protein digestion has occurred, will the solution be violet or pink (choose one)? Hypotheses/Predictions (See Methods section for details): What color do you expect the solution to turn when the P tubes are mixed with Biuret solution and why? P1 P2 P3 P4 The least protein digestion (or none at all) will take place in tubes…
