Key metabolic processes - Biochemical pathway map

"Metabolism is refer to all chemical reactions that occur in living organisms, including digestion and the transport of substances into and between different cells. Metabolism is usually divided into catabolism, that breaks down organic matter and harvests energy by way of cellular respiration, and anabolism that uses energy to construct components of cells such as proteins and nucleic acids.
The chemical reactions of metabolism are organized into metabolic pathways, in which one chemical is transformed through a series of steps into another chemical, by a sequence of enzymes." [Metabolism. Wikipedia]
