Energy and metabolism are intimately linked in living beings. Metabolism encompasses all the biochemical processes that convert food into energy, enabling growth, reproduction, and maintenance of cellular functions. Within metabolic pathways, catabolic reactions break down organic matter to release energy, while anabolic reactions utilize this energy to synthesize essential compounds. Thus, energy fuels metabolic activities essential for the homeostasis of organisms, allowing them to respond and adapt to their environments effectively. In this way, a continuous supply of energy is crucial for sustaining life.
