The Metabolic Pathway
Captions available
The idea
A metabolic pathway is a series of interconnected reactions, each catalyzed by its own enzyme, that converts a starting substrate into a final product through intermediate steps.
In practice
Glycolysis is a ten-step metabolic pathway converting one glucose molecule into two molecules of pyruvate.
Where people slip
A pathway's intermediates are not waste — many feed directly into other pathways elsewhere in the cell.
