In the process of dissimilation, 7 moles of glucose were cleaved, of which only 2 moles underwent complete (oxygen) cleavage.

In the process of dissimilation, 7 moles of glucose were cleaved, of which only 2 moles underwent complete (oxygen) cleavage. Determine how many moles of lactic acid and carbon dioxide were formed? How many moles of ATP have been synthesized? How many moles of oxygen should be added for the complete oxidation of lactic acid formed under these conditions?

To solve this problem, we use two dissimilation equations:
1) glycolysis:
C6n1206 + 2H3R04 + 2ADP + 2NAD + ->
-> 2C3H403 + 2NAD • H + 2H20 + 2ATF;
2) complete oxidation of glucose:
C6H1206 + 602 + 38ADP + Z8H3PO4 -> 6CO2 + 6H20 + 38ATF.
If 2 moles of glucose undergo complete oxidation, then 5 moles are incomplete oxidation. According to the first equation, from 5 moles of C6H12O6, 10 moles of lactic acid and 10 moles of ATP are obtained. According to the second reaction equation, from 2 moles of C6H12O6, 12 moles of CO2 and 76 moles of ATP are formed. The total is 86 moles of ATP. For the complete oxidation of glucose (5 moles), another 5 * 6 = 30 moles of 02 will be needed.
Answer. 10 moles of lactic acid; 12 moles of CO2; 86 moles of ATP; 30 moles 02.
