Suppose that you have been working with a research team focused on lysosomal storage diseases (LSDs). The team has recently completed an experiment in which fibroblasts taken from participants who have a lysosomal storage disease were used to evaluate two new potential drug treatments.

The experiment consisted of growing the cells in the laboratory for 24hours, at which point the growth media was modified by addition of either saline (a solution of sterile water mixed with a low concentration of salts that should have no physiological effect) or one of the two new drug treatments (drugA or drugB, both of which were administered by being dissolved in an identical saline solution) for another 24hours. Following the treatment phase and loading of the cells with TMRE, the fluorescence intensity of the cells was measured.

The data generated by this experiment are plotted in Figure3:
