Final answer:
Catabolic pathways break down molecules like glucose and fats to produce ATP, which is essential for cell energy. These molecules undergo reactions to release energy for ATP generation.
Explanation:
Catabolic pathways involve breaking down complex molecules into simpler ones to release energy for ATP production. Molecules like glucose and fats undergo catabolic reactions to generate ATP. ATP serves as a vital energy source for cells, derived from the breakdown of these energy-storing molecules.
