Light Reaction Ribulose Bisphosphate Triose Phosphate Carbon Dioxide

The stages of the light-independent reaction involve carbon dioxide fixation with ribulose-1,5-bisphosphate catalyzed by rubisco, reduction of glycerate 3-phosphate to triose phosphate using ATP and reduced NADP, regeneration of ribulose-1,5-bisphosphate from triose phosphate using ATP, and production of organic compounds.

Etapele reacției independente de lumină includ fixarea dioxidului de carbon cu ribulozo-1,5-bifosfat catalizată de rubisco, reducerea gliceratului 3-fosfat la triozo-fosfat folosind energie din ATP și NADP redus, regenerarea ribulozo-1,5-bifosfatului din triozo-fosfat folosind ATP, și producerea de compuși organici.

Front Describe the stages of light independent reaction
Back Carbon dioxide enters through stomata and dissolves into water and diffuses across cell surface membrane and into the stroma

Carbon dioxide reacts with ribulose bisphosphate which is catalyzed by enzyme ribulose bisphosphate carboxylase (rubisco) and produces x2 glycerate 3-phosphate

Reduced NADP reduces glycerate 3-phosphate to triose phosphate using energy from ATP

NADP reformed and goes back to light dependent reaction to be reduced again

Some triose phosphate used to produce organic materials such as glucose

Most triose phosphate used to regenerate ribulose bisphosphate using ATP from light dependent reaction
