- 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.nfile.php/7382360/mod_resource/content/0/Pyrimidine%20Practice%20Pat 1 / 1 67% + | 田 Pyrimidine Synthesis El * be surc to label reguletary Steps K carbamay1 phiuphate E2 orotate R-5P Eg UMP d TMP ATP ADPEE3 TET EedUDP O dumP E4 E5 CTP-> dCDPbiochemistry question, please show all work! As the result of a storm while on a three-hour boat tour, you have found yourself on an uncharted island with several other people. The (additional) bad news is that you and your fellow castaways have become infected with a previously unknown, lethally pathogenic organism, P. Fortunately, however, you have discovered a biochemistry laboratory on the island, and you begin to study the organism. In Organism P, the ATP synthase enzyme complex can synthesize ATP using a proton gradient, and can use ATP hydrolysis to generate a proton gradient. For Organism P you measure: pHinside = 8.5, pHoutside = 7.3, and membrane potential = –110 mV.a. Assumingthatthebacteriumisaspherewithadiameterof2.34μm,howmany “free protons” are present in the cell?b. Assuming [ATP] = 5 mM, [ADP] = 1 mM, and [Pi] = 2 mM, and the cellular temperature is 25°C, what is the minimum number of protons that must enter the cell to yield enough energy to synthesize an ATP from an…
