Questions;
Thomas was purifying an enzyme from a homogenate of muscle cells. He went through seven steps of purification and found that the enzyme activity was the same as the homogenate value. On the eighth step, when the protein washighly pure, the enzyme activity rose to five times that of the homogenate value. Can you suggest a possible reason?
A. the homogenate assay was wrong
B. step eight has co-purified an activator of the enzyme.
C. the enzyme has an inhibitor present in the muscle cell homogenate
D. the temperature at step eight was just right for the enzyme activity.

- Question: Explain: Lipids supply more than twice as many calories as carbohydrates. Based on the results of the Sudan dye III experiment, which will supply more lipids, honey, or vegetable oil? Why?arrow_forwardMATHEMATICAL An organic chemist is generally happy with 95% yields. If you synthesized a polypeptide and realized a 95% yield with each amino acid residue added, what would be your overall yield after adding 10 residues (to the first amino acid)? After adding 50 residues? After 100 residues? Would these low yields be biochemically satisfactory? How are low yields avoided, biochemically?arrow_forwardStudy problem 2 4. A coworker has just isolated a copper enzyme that catalyzes the conversion of oil sludge into soluble alcohols in the presence of O₂. There are two Cu atoms per protein, which consists of a single polypeptide chain. As the bioinorganic chemist on the project, you are given unlimited quantities of the protein for the purpose of determining the active site structure. You have at your disposal a number of physical techniques, including NMR and EPR spectrometers, a magnetic susceptometer, a Mössbauer instrument, an X-ray absorption beam line, a UV-VIS spectrophotometer, a Raman spectrometer, a magnetic circular dichroism instrument, but, alas, no X-ray diffractometer. You have time to complete measurements by only three techniques before you have to give a report to your colleague. Describe what measurements you would make, in what order you would make them to get the most out of time, what results you might expect, and how you would use this information to characterize…arrow_forward
