What term describes the chemical processes in living organisms where cells are nourished and carry out their activities?

• A. Respiration
• B. Metabolism
• C. Photosynthesis
• D. Digestion

Answer: (B)

The correct term that describes the chemical processes in living organisms, where cells are nourished and carry out their activities, is metabolism. Metabolism encompasses all the biochemical reactions that occur within an organism, including the conversion of food into energy, the synthesis of necessary compounds, and the breakdown of waste products. This term is crucial as it highlights the complex network of reactions that not only provide energy for the body’s functions but also enable growth, reproduction, and maintenance of cellular functions. Metabolism is divided into two main categories: catabolism, which breaks down molecules to release energy, and anabolism, which builds up cellular components. This comprehensive understanding of metabolism is essential for professionals in the beauty and health fields, as it relates to skin and nail health as well as overall wellness. In contrast, respiration is specifically related to the process of converting oxygen and glucose into energy, mainly within cells. Photosynthesis is a process specific to plants that converts light energy into chemical energy. Digestion refers specifically to the process of breaking down food into smaller components for absorption. While all these processes are vital for an organism's survival, metabolism is the overarching term that encompasses all of them, making it the correct choice for the question.
