Which two solutions need to be present to produce the brown-colored Benzedrine? Potato extract and cathode need to be present What substance is not present in tube 52 for the production of the brown- colored substance? Cathode What substance is not present in tube SO for the production Of the brown- colored substance? Potato extract II. Enzyme Specificity EXERCISE 2 – Enzyme specificity At five and ten minute intervals, record the color intensity in each test tube. Time Tube 1 with cathode Tube 2 with hydrogenous Based upon color intensity, to What degree does cathode oxides react With hydrogenous? 4
What difference in chemical Structure Of the two substrates determines the specificity of cathode oxides? The different location of the second . OH group Ill. Temperature and Enzyme Activity EXERCISE 3 – Enzyme activity and temperature Record the relative color intensity at intervals dative and ten minutes. Time Tube 1 ICC Tube 2 ICC Tube 3 400 C Tube 4 ICC Tube S ICC Tube 6 1 coo Double click the chart below. A spreadsheet will open.
