Exergonic chemical reactions release more energy than they absorb and the catabolism of the food in an energy bar serves as an example. c. The many forms of energy used up by cells comes from the breakdown of the chemical energy from the food we digest.Breaking large molecules into smaller ones is catabolic and releases energy. Conversely, building large molecules from small ones is anabolic and consumes energy.
