which process is the total of all the chemical reactions in an organism?
Answer: The process that encompasses all the chemical reactions occurring within an organism is called “metabolism.” Metabolism includes various biochemical processes that involve the conversion of molecules into energy and the synthesis of essential compounds necessary for the growth, maintenance, and functioning of living organisms.
Metabolism can be divided into two main categories:
-
Catabolism: This involves the breakdown of larger molecules into smaller ones, often releasing energy in the process. For example, the breakdown of carbohydrates, fats, and proteins to produce energy is a catabolic process.
-
Anabolism: This involves the synthesis of larger molecules from smaller ones, often requiring energy input. Anabolic processes are responsible for building and repairing cellular structures and molecules.
Together, catabolism and anabolism make up the entirety of the chemical reactions that sustain life within an organism.
