Final answer:
Physical exercise involves both anabolic and catabolic processes. Anabolic processes build up molecules and require energy, while catabolic processes break down molecules to release energy.
Step-by-step explanation:
Physical exercise involves both anabolic and catabolic processes. Anabolic processes involve building up molecules and require energy, while catabolic processes involve breaking down molecules to release energy. For example, during exercise, anabolic processes are responsible for building muscle tissue, while catabolic processes break down glucose to release energy. Both processes are essential for maintaining a healthy body and are part of the body's overall metabolism.
