Metabolism
Public Group active 4 days, 11 hours agoMetabolism (from Greek: μεταβολ “change” or Greek metabolismos, “outthrow”) is the set of chemical reactions that happen in the cells of living organisms to sustain life. These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environments. Metabolism is usually divided into two categories. Catabolism breaks down organic matter, for example to harvest energy in cellular respiration. Anabolism uses energy to construct components of cells such as proteins and nucleic acids.
