However, cells grown solely on TMG will not grow, and will instead eventually die. Based on the structures provided below, why are cells capable of growing on ONPG and lactose, but not TMG alone?THIS IS A MULTIPART QUESTION, PLEASE ANSWER ALL THANK YOU You are studying two bacterias, bacA and bacB. bacB has increased levels of peroxidase but no catalase. On the other hand, bacA has increased levels of catalase but no peroxidase. For the first experiment, you add both bacA and bacB in a buffer containing hydrogen peroxide and NO iron. After analyzing the amount of hydrogen peroxide after 1 hr in the buffer alone, then buffer with bacA, then buffer with bacB, the data below is shown. A. Oxygen levels are also being measured in each of the 3 conditions from the experiment above. Create a graph of the expected O2 level results, explain the rationale and label title with axis B. Graph the expected NAD+ level results in the 3 conditions present, explain rationale and label title with axis C. On the second experiment, everything was repeated like the first however, this time iron was added to the buffer. Create a graph of the expected oxygen levels after the addition to iron…helping tags: Biochemistry, spectrophotometric analysis, enzyme, substrate, coenzyme Will upvote, just pls help me answer the table.
