What does it mean that the breakdown of glucose is exergonic and catabolic?

Catabolism refers to the exergonic process by which energy released by the breakdown of organic compounds such as glucose can be used to synthesize ATP, the form of energy required to do cellular work. Aerobic respiration is an exergonic pathway that requires molecular oxygen (O2).
