What are th combination of chemical reactions make up an organisms?

The combination of chemical reactions that make up an organism is primarily defined by metabolism, which includes two main types of reactions: catabolic and anabolic. Catabolic reactions break down complex molecules into simpler ones, releasing energy in the process, while anabolic reactions utilize that energy to build complex molecules from simpler ones, essential for growth and repair. These biochemical pathways are facilitated by enzymes and are crucial for maintaining homeostasis and supporting life functions. Additionally, these reactions are interconnected, forming intricate networks that sustain cellular processes.
