WebAug 1, 2011 · This is an average rate of oxygen utilization of 2.5 × 10 − 18 mol cell − 1 s − 1, i.e., 2.5 amol cell − 1 s − 1. Cells have a wide range of oxygen utilization, depending on cell type, function, and biological status. Measured rates of oxygen utilization by mammalian cells in culture range from < 1 to > 350 amol cell − 1 s − 1.
