In order to ensure complete digestion of proteins, a proteolytic enzyme such as pepsin may be used. However, this enzyme requires appropriate temperature and a low (acidic) pH to be active. Thse conditions in a test tube will replicate the conditions in a mammalian stomach where in presence of acidic conditions(HCL, pH=1.5-3.5) and the proteolytic enzyme, pepsin. Further, the human body temperature is 37 degree celsius and thus, the test tube must be incubated at a similar temperature. Once all these conditions are met, complete digestion of proteins will occur and a clear tube will be obtained.
for the test tubes that had protein digestion, what needs to occur to get the test...
9 Interpret your results: a In which tube(s) did protein digestion occur? How do you know? b In which tube(s) did no protein digestion occur? How do you know? c What effect does pH have on protein digestion with pepsin? Why? d What other effects does acid have in the stomach? Procedure 3 Demonstrate Lipid Emulsification Let's examine what happens during the process of emulsification. In this exercise you will use four substances to observe emulsification in action: 1 Lipids:...
Making the Alternative and Null Hypotheses Statements Austin’s company manufactures test tubes. He needs his tubes to be exactly 4.0 mm in diameter. If they are too narrow or too wide, he must recalibrate his machine. Austin randomly measured 150 tubes off the production line in order to perform a hypothesis test.
You want to test the effects of different antibiotics on protein synthesis. You set up three test tubes to carry out protein synthesis in vitro. After letting protein synthesis proceed, you add the following to the tubes: Tube A - No antibiotic Tube B - Antibiotic B Tube C - Antibiotic C (1) Please state the results shown below. (2) Given the results, which step of translation may be most likely affected by Antibiotic B? Explain your answer. (3) Give...
A tube feeding formula is 9% protein by volume. The patient needs 80 grams of protein per day. How much formula should this patient get per day?
Suppose you filled one test tube with alanine and a second test tube with casein, but forgot to label the test tubes. What test could you run on the samples to confirm which test tube contained the alanine? Explain.
Please give me answers..
2. What other ways might be used to close test tubes, still retaining a sound bacteriologic technique? 3. How would you protect culture medium from lint in a liter Erlenmeyer flask in which the cotton plug had to be large? 4. Explain your preference of method for the sterilization of : A hypodermic needle, rubber gloves, talcum powder, paraffin oil, a soldered test tube rack of metal, plugged test tubes, a package of surgical gowns, an...
What was the most likely treatment for digestion of the unknown protein, why? The unknown is: Beta sliding clamp I am not sure how to answer this question.
Suppose you were given four (4) test tubes, labeled A, B, C, and D. Each containing a colorless solution. In each of the following questions (1-3), indicate which of the solutions listed could be used to distinguish between the pairs of solutions. Use your solubility rules to help you make a choice. 1. Test tube A contains 0.1M NaNOs solution and test tube B contains 0.1M BaNOsl solution. 2. Test tube C contains 0.1M NaCl solution and test tube D contains 0.5M...
Question 31 1 pts What happens to protein digestion products in the gastrointestinal tract? The products are packaged into micelles during absorption All of the amino acids are used metabolically by the enterocyte O The protein digestion products are moved into the central lacteal Some of the amino acids are used during protein synthesis in the enterocyte The amino acids are combined with carbohydrates to form glycoproteins Question 29 1 pts In the gastrointestinal tract, retropulsion... forms feces in the...
