Answer: The totality of an organism or cell's metabolic reactions is referred to as "metabolism." Metabolism includes all the chemical processes that occur within an organism to maintain life, such as energy production, growth, reproduction, and the regulation of various cellular activities. It can be further divided into two main categories:
Catabolism: This involves the breakdown of complex molecules into simpler ones, typically releasing energy in the process. An example is the breakdown of glucose during cellular respiration.
Anabolism: This involves the synthesis of complex molecules from simpler ones, requiring energy input. An example is the synthesis of proteins from amino acids.
