Diagram of the reductive pentose phosphate cycle in photosynthesis, showing carbon dioxide fixation and reduction steps. Arrows trace the transformation of CO2 and RuBP through intermediates like PGA, DPGA, and Gal3P, with ATP and NADPH inputs and the net production of one Gal3P molecule for sugar or starch synthesis.

Quick Summary

C3 carbon fixation pathway Pathway of carbon dioxide fixation and reduction in photosynthesis, the reductive pentose phosphate cycle. The diagram represents one complete turn of the cycle, with the net production of one molecule of Gal3P. The nine molecules of ATP and six molecules of NADPH come from the light reactions.

Glyceraldehyde 3-phosphate (Gal3P) is a three-carbon sugar phosphate that plays a crucial role in both photosynthesis and cellular respiration. In photosynthesis, it is a product of the Calvin-Benson cycle, where it is used to build glucose and other carbohydrates. In cellular respiration, Gal3P is an intermediate in glycolysis, the process by which glucose is broken down to produce energy. It is formed from the splitting of fructose 1,6-diphosphate and is then further processed to generate ATP, the main energy currency of cells.1234
