Change: the molecule and splits it into two smaller molecules.Metabolic Pathways can be linear, branched (divergent or convergent), or cyclic. Many enzymes are present, each one makes a product that becomes a reactant, that is the reactant for the next protein, A to B to C to D etc. Bioenergetics   View changes from previous version.
