Metabolism: network of chemical processes that maintain life.

Metabolic pathway: biochemical reactions that occur in progression from beginning to end.

Intermediates: Compounds formed in a pathway.

Anabolic: pathways that build compounds.

Catabolic: pathways that break down compounds.

ATP: Body's source of energy derived from catabolic reactions.

ATP is broken down to ADP or AMP to generate energy.

*ATP possess a high energy bond.

Stage 1: Digestion-breakdown of complex molecules to their component building blocks.

Stage 2: Conversion of building blocks to acetyl-CoA (Krebs cycle or CAC)

Stage 3: Metabolism acetyl-CoA to CO^2 and formation of ATP.
