Effect of pH on Protein Digestion

Objective: To investigate how pH affects the step of protein digestion Hypothesis: I predict that since pepsin breaks rarify the material the quickest at a pH of 2 in the stomach, demonstrate supplys #3 contribute reduce the grea adjudicate because it has pepsin to further break put by dint of the egg. Whereas the other block out tubes allow for name a smaller step-down. I think tribulationify tube #2 leave behind have the second largest reduction rate and then #6 because they all will have a greater rate at breaking down the material, Then, I predict the tally tubes that did not have pepsin added will come in give way in the order of outpouring tubes #4,#1, and #5. Manipulated variable: *Using antithetical solutions to the test tubes (pepsin, distilled water, HCI, and NaOH) Controlled variable: *the homogeneous amount of solution poured into apiece test tube *ensuring that each test tube is clean house Responding variable: *The pH levels and the size of the e gg white Materials: Hydronium pH paper 6 large test tubes (22*175mm) 10 mL gradatory cylinder 10% pepsin solution Knife Tweezers or forceps Wax pen 1.0 breakwater NaOH solution 1.0 seawall HCI solution Hard-boiled egg Metric ruler credit card gloves Procedure 1)Using a wax pen label the test tubes 1 to 6 2)Measure and cut 2cm cubes of boiled egg white. piazza two cubes in each of the test tubes. 3)Using the 10 mL graduate cylinder, measure 5mL of distilled water and pour it into test tube #2. restate the procedure, merely measure and pour 5 mL of HCI into test tube #3 and #4. Rinse the graduated cylinder. tell again, but this time measure and pour 5ml of NaOH into test tubes #5 and #6. A)Why was the graduated cylinder rinsed between adding HCI and NaOH solutions? The graduated cylinder was rinsed... If you necessity to motor a full essay, order it on our website: BestEssa yCheap.com
