Final answer:
Respiration is a catabolic and exergonic process that breaks down molecules into smaller units and releases energy.
Step-by-step explanation:
Respiration is a catabolic and exergonic process. Catabolic reactions break down molecules into smaller units, while exergonic reactions release energy. The breakdown of glucose during cellular respiration is an example of a catabolic and exergonic reaction as it breaks down glucose and releases energy needed for cellular functions.
