Answer: The term that refers to the combination of all the chemical reactions in cells that use or release energy is metabolism.
Step-by-step explanation:
Metabolism is the set of biochemical processes that occur in living organisms to maintain life. It includes all the chemical reactions involved in the breakdown of molecules to obtain energy (catabolism) and the synthesis of molecules to build and maintain cellular structures (anabolism).
During catabolic reactions, larger molecules are broken down into smaller molecules, releasing energy in the process. This energy can be used to perform various functions in cells, such as powering muscle contractions, maintaining body temperature, and facilitating the transport of molecules across cell membranes.
Anabolic reactions, on the other hand, involve the synthesis of complex molecules from simpler ones, requiring energy input. These reactions are responsible for building macromolecules like proteins, nucleic acids, and carbohydrates, which are essential for cell growth and repair.
Overall, metabolism encompasses all the chemical reactions in cells that involve energy transfer. It plays a crucial role in the functioning and survival of organisms.
