Summary

The oxygen consumption rate \(\left( \dot{Q}{{O}_{2}} \right)\) of EMT6/Ro-cells cultured as monolayers was investigated as a function of their proliferative status. The transition of these cells from the exponential to the plateau growth phase was associated with a continuous decrease in \(\dot{Q}{{O}_{2}}\) per single cell. This decrease can partially be attributed to a corresponding decline in cellular volume. In addition, the \(\dot{Q}{{O}_{2}}\) per cell volume was also reduced during the passage of the cells through the growth phase described. The results lead to the conclusion that a reduction in cellular volume and factors which are still unknown may contribute to the metabolic changes observed.
