Definition

The term metabolic pathway is used to refer to a series of chemical reactions occurring within the cell of a living organism. Typically, it refers to reactions controlled and regulated by the cell, with enzymes used for catalysis.

The end products of a metabolic pathway may be used in either of three ways:

  1. Immediate use for cellular functions
  2. Input to another metabolic pathway
  3. Storage for later use
