The developmental evolution of fluxes diverging at the intermediate metabolite listed in the first column, when normalized by the total flux entering the branch point, can be described as monotonically increasing (↑↑), increasing with minor variations (↑), essentially unchanged (—), decreasing with minor variations (↓), or monotonically decreasing (↓↓).
