All chemical processes that take place in living organisms is known as?

The term that encompasses all chemical processes occurring within living organisms is metabolism. Metabolism refers to the entirety of biochemical reactions that involve the conversion of food into energy, as well as the synthesis of necessary compounds for cellular function and maintenance. This includes a vast range of processes, from breaking down nutrients to generate energy (catabolism) to the building of complex molecules from simpler ones (anabolism). Thus, when we refer to metabolism, we are talking about both the breakdown of substances to extract energy and the processes that build up the components necessary for life. This broad classification makes metabolism the correct answer, as it correctly identifies the overall set of processes rather than a specific subset.
