Answer:
Glucose -Glycolysis
6O2 -  pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation
CO2 - kerbs cycle  
Water- electron transport chain.
ATP - glycolysis, pyruvate oxidation & kerb cycle
Explanation:
Glucose (C6H12O6) is used in Glycolysis
6O2 is used in pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation
CO2 is produced in kerbs cycle in which 2 CO2 molecules are produced every single molecule of acetyl CoA
Water is produced in electron transport chain.
ATP is produced in following stages
a.	The 6 ATP or 2 NADH molecules from glycolysis  
b.	The 6 ATP or 2NADH molecules from pyruvate oxidation  
c.	The 18 ATP or 6 NADH molecules from Krebs’ cycle  
d.	The 4 ATP or 2 FADH2 molecules from Krebs’ cycle
