To determine which aspect of carbon catabolism was impacted by mutagenesis in each of these strains, the strains were also assayed for carbon catabolism of glucose, xylose and arabinose and sent for genetic sequencing. It was found that PET #X had a mutation that resulted in constitutive CAP binding to the CAP binding site. Which of the graphs below is most likely to represent strain PET #X?
