An animal cell, roughly cubical in shape with side length of 10 μm, uses 109 ATP molecules every minute. assume that the cell replaces this ATP by the oxidation of glucose according to the overall reaction 6O2 + C6H12O6 →6CO2 + 6H2O and that complete oxidation of each glucose molecule produces 30 ATP molecules. how much oxygen does the cell consume every minute? How long will it take before the cell has used up an amount of oxygen gas equal to its own volume?
