biochemistry - Energy released during the production of ATP?

When glucose is used during aerobic and anaerobic exercise, how much energy is expended or required?

During aerobic exercise:

$C_6H_{12}O_6 + 6 O_2 \to ATP + H_2O + 6 CO_2$ + energy

During anaerobic exercise:

$C_6H_{12}O_6 + 6 O_2 \to 2 C_3H_6O_3 + 2 ATP$ + energy

For each of the reactions above what is the value of the '+ energy' part?
