Adenosine triphosphate (ATP) connects anabolism and catabolism in cells by storing energy from catabolic reactions and providing that energy to anabolic reaction.
Adenosine triphosphate (ATP), also known as energy molecule, is found in animal and plants cells.
It plays a huge role in anabolic and catabolic reactions.
During anabolic reaction, simple organic molecule join together to form complex molecule by using energy.
For example, carbohydrates, fats, proteins and glycerol.
While in catabolic reaction, large complex molecules disintegrate to form small molecule and in this reaction a large amount of energy is released. 
This energy is stored by the body cells for later use.
