Cells can cooperate to get the oxygen to other cells, but nor cell can make ATP and donate it to another cell. When it comes to the production of ATP, each cell is on its own. The overall chemical formula for aerobic (oxygen using) cell respiration is: C6H12O6 + 6 O2 --------> 6 CO2 + 6 H2O + Energy (ATP) Normally, aerobic cell respiration is broken down into three parts. Glycolysis--The breakdown of a glucose molecule into two three-carbon pieces called pyruvate. You will notice that very little ATP is produced in this step and no oxygen is required.
