Metabolism is a vast interlocking web of chemical reactions. If you put your finger on one of the dots (in the following figure) that represents a particular chemical, you can trace a path from that dot, along lines, to other dots, and so on. The path your finger travels represents a subset of the many chemical reactions that are occurring in the cell.
