1. What background information about biology did you need to know to complete these experiments? (e.g., big-picture stuff – a sentence or two relating to the introduction given in the lab instructions PDF) It would have been helpful to know about protein digestion and other digestive processes 2. What did you test? State your hypothesis. we tested proteins and modeled digestion of starch and protein; If the test tube is kept in warmer conditions, then digestion will occur faster. 3. How did you test it (briefly describe your methods)? What were your variables and constants? We mixed distilled water with several chemicals at different temperatures and with some household foods to model the way proteins and enzymes help us to digest; the variables were the chemicals and temperature, the constants were the distilled water 4. What did you find? Explain your results. We found that chemical changes occurred. In testing for lipids we found that only water and grapefruit juice had a negative result, which means they do not contain much fat. © 2016 Carolina Biological Supply Company

6 5. What do your results mean and why might they be important? as far as the protein digestion test with the varying temperatures, the hotter temperature had completely separated the two solvents and they did not mix, which maybe shows how digestion takes place in animals Photos Photo 1 + Insert the photo from Activity 1, step 5. The following should be indicated in this photo: Test Tube 1 – water Test Tube 2 – starch Test Tube 3 – albumin © 2016 Carolina Biological Supply Company

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
