Cells use the hydrolysis of adenosine triphosphate, abbreviated as ATP, as a source of energy. Symbolically, this reaction can be written as

$ATP(aq)+H_{2}0(l)- > ADP(aq)+H_{2} PO\frac{}{4} (aq)$

where ADP represents adenosine diphosphate. For this reaction, a. Calculate at b. If all the free energy from the metabolism of glucose

$C_{6} H_{12}O_6(s)+6O_2(g)- > 6CO_2(g)+6H_2O(l)$

goes into forming ATP from ADP, how many ATP molecules can be produced for every molecule of glucose?

$C_6H_1_2O_6(s)+O_2(g)- > 6CO_2(g)+6H_2O(l)$

goes into forming ATP from ADP, how many ATP molecules can be produced for every molecule of glucose?
