What is the phase of metabolism that involves breaking down complex compounds within cells into smaller ones?

• A. Synthesis
• B. Anabolism
• C. Catabolism
• D. Homeostasis

Answer: (C)

The correct answer is catabolism, which refers to the metabolic phase that involves the breakdown of complex molecules into simpler ones, releasing energy in the process. This phase is essential for cells as it helps in the recycling of cellular components, generating energy from nutrients, and providing the building blocks necessary for various cellular functions. During catabolism, larger molecules such as carbohydrates, fats, and proteins are dismantled into their constituent parts—like glucose, fatty acids, and amino acids—enabling the body to utilize these smaller molecules for energy or to recombine them for other functions. This breakdown is vital for maintaining the energy balance and supporting activities such as muscle contraction, nerve transmission, and cellular repair. In contrast, synthesis and anabolism refer to the construction or building up of complex molecules from simpler ones, typically requiring energy input, while homeostasis refers to the overall balance and regulation of physiological processes in the body to maintain a stable internal environment. Understanding these metabolic processes is crucial for comprehending how the body generates and uses energy.
