What term refers to all the chemical reactions in a living thing?

• A. Metabolism
• B. Pest
• C. Organism
• D. Monitoring

Answer: (A)

Metabolism is the term for all the chemical reactions that occur in a living thing. These reactions include breaking down molecules to release energy (catabolism) and using energy to build up larger molecules (anabolism). Enzymes act as catalysts to speed up these processes, and energy carriers like ATP move energy where it’s needed. Metabolism integrates nutrient uptake, energy production, growth, repair, and responses to the environment. The other terms refer to a single organism or an activity, not to the whole set of biochemical reactions happening inside living systems.
