is the chemical reactions that break down complex organic molegucles into simpler ones
catabolic reactions are exergonic (they produce more energy than they consume)
Important sets of catabolic reactions occur in glycolysis, krebs cycle, and the electron transport chain
40% of energy released during catabolism is used for cellular function; the rest converted to heat

chemical reactions that combine simple molecules and monomers to form the body's complex structural and functional components
Ex. Anabolic reactions are the formation of peptide bonds between amino acids during protein synthesis, building of fatty acids into phospholipids that form the plasma membrane bilayer and th elinkage of glucose monomers to form glycogen
Reactions are endergonic; (they consume more energy than they produce)
Molecule synthesized in anabolic reaction has a limited lifespan, ecept it will be broken down and its atom recycled into other molecules or excreted from the body

participates most in energy exchanges
couples energy releasing catabolic reactions to energy requiring anabolic reactions
Both catabolic/anabolic reactions can occur at the same time
The energy currency of a living cell
About a billion molecules of ATP per cell
ATP consists of adenine molecule, ribose molecule, and three phosphate groups bond to each other.
ATP links anabolic/catabolic reactions
When terminal phosphate group is split off ATP, adenosine diphosphate (ADP) and a phosphate group are formed. Which then during the catabolic reaction combine ADP and the phosphate group to resynthesize ATP
Some of the energy released during oxidation reaction is captured when ATP is formed. A phosphate group is added to ADP with an input of energy to form ATP. This addition of phosphate group called phosphorylation increases its potential energy
