22. PENTOSE PHOSPHATE PATHWAY Functions
Generate reducing potential in the form of NADPH. It serves as an electron donor and drive biosynthetic reactions in the cytosol.
The production of pentose phosphate, precursor for ribose and deoxyribose => nuclei acids.
Erythrose-4-P precursor biosynthesis of aromatic aminoacids, lignin and flavonoids
