**Oxygen Consumption in Melanoma Cell Lines Post Treatment** **Figure 2: Oxygen consumption per cell in four melanoma lines after treatment with either solvent alone or solvent containing drug X.** This bar graph illustrates the oxygen consumption (pmol O₂ consumed per cell) in four different melanoma cell lines (Cell Line 1, 2, 3, and 4) following treatment. The graph compares the effect of two different treatments: solvent alone (represented by unshaded bars) and solvent with drug X (represented by shaded bars). - **X-axis (horizontal)**: Represents the four different melanoma cell lines labeled as Cell Line 1, Cell Line 2, Cell Line 3, and Cell Line 4. - **Y-axis (vertical)**: Indicates the amount of oxygen consumed per cell after treatment, measured in picomoles (pmol O₂)/cell. Key observations: - **Cell Line 1**: Treatment with solvent alone shows an oxygen consumption of about 0.2 pmol O₂/cell, while solvent with drug X shows approximately 0.05 pmol O₂/cell. - **Cell Line 2**: Solvent alone results in high oxygen consumption (~0.5 pmol O₂/cell), whereas solvent with drug X significantly reduces the oxygen consumption to about 0.1 pmol O₂/cell. - **Cell Line 3**: Solvent alone results in ~0.3 pmol O₂/cell while solvent with drug X reduces it to about 0.1 pmol O₂/cell. - **Cell Line 4**: Solvent alone records an oxygen consumption of ~0.3 pmol O₂/cell, and this decreases to approximately 0.1 pmol O₂/cell with solvent and drug X. The error bars represent ± 2 standard errors of the mean (2SE). This data suggests that drug X consistently reduces oxygen consumption across all four melanoma cell lines when compared to the solvent alone treatment, indicating its potential impact on cellular respiration in these melanoma cells.
