he main pathway for oxidation of carbohydrates, synthesized during photosynthetic ‘carbon fixation’, is glycolysis
followed by the TCA cycle. However alternative oxidative pathways such as the oxidative pentose phosphate pathway
(OPP), formerly called the hexose monophosphate shunt or phosphogluconate pathway. See Biochemistry of Lactic Acid
Bacteria: Heterofermentative Metabolism of Hexoses and Figure 2.
This pathway is involved with the interconversions and rearrangements of sugar phosphates with the net production of
NADPH.
