Why must the release of energy during the cellular process in which atp is made from glucose take place in small steps?

Cellular respiration is a process of converting the biochemical energy into ATP that can be used by the body as an energy source to all metabolic works.  The process of cellular respiration is generally summarized as:

C6H12O6 (s) + 6 O2 (g) → 6 CO2 (g) + 6 H2O (l) + heat

 `Delta` G = −2880 kJ per mol of C6H12O6

This process is not straightforward. There are series of complicated reactions that converts 1 mole of glucose into its products. 2880 kJ of energy is so much for a particular organism to carry. No one can actually survive from an attack of that amount of energy. If the reaction is not step-wise, the amount of energy cannot be contained in the body thus the metabolism is not possible.
