MnSOD over-expression extends Drosophila lifespan and alters metabolic rates. For these assays four lines were used: control, MnSOD(2)22, MnSOD(2)20, and MnSOD(2)12. (a) The percentage of animals alive is plotted against animal age. (b) Plots of log mortality rate against age. (c) CO₂ production as measured by the average nanoliters of CO₂ produced per minute plotted against age.
