How is the process of anabolism carried out in a cell of a living organism?

Anabolic pathways in the cell lead to the formation of larger, more complex molecules from smaller ones. First, catabolic pathways are required to break down nutrient molecules from food into small building blocks. These smaller molecules then combine with each other to form different large molecules called macromolecules. Anabolic pathways include the energy that is needed to form chemical bonds between smaller molecules to make macromolecules. The molecules built from anabolism are then used to build structures in the cell, or even to create new cells. Anabolism and catabolism are controlled by circadian rhythms, and both are important for the development, growth, and maintenance of body cells.
