It participates in both the pentose phosphate pathway in all organisms and the Calvin cycle of photosynthesis. Transketolase catalyzes two important reactions, which operate in opposite directions in these two pathways.

WebThe pentose phosphate pathway (PPP) is an alternative way of glucose use. It consists of an aerobic and an anaerobic part. For that reason, the PPP can act as a pathway or a cycle both at the same time. Its aerobic part leads to ribulose-5-phosphate, carbon dioxide (CO2 ), and reduced nicotinamide adenine dinucleotide phosphate (NADPH).
