In the reactions of glycolysis, acetyl-coa formation and the citric acid cycle, chemical energy is transferred to the bonds in:

The energy gets stored in two molecules:
NADH and ATP. 

NAD+ recieves an H, and the energy is stored in that bond.
ADP recieves a P (phosphate) and the energy is stored in that bond. 

ATP can then be used as an energy source in the cell, but NADH gets used to make more ATP in the oxidative phosphorylation.
