Final answer:
Catabolic reactions break down larger molecules to release energy, while anabolic reactions use energy to build larger molecules. Both pathways are vital for maintaining the cell's energy balance.
Explanation:
Catabolic reactions involve breaking down larger molecules into smaller ones, releasing energy in the process. For example, the breakdown of carbohydrates, lipids, and proteins into simpler components is a catabolic process that releases energy.
In contrast, anabolic reactions require energy to build larger molecules from smaller ones. These processes are essential for cellular growth and repair.
Both catabolic and anabolic pathways play crucial roles in maintaining a cell's energy balance and are necessary for various metabolic functions.
