How light controls the assembly of chloroplast enzymes into supramolecular complexes?

a.) Light regulates the stability of the ternary complex through the ferredoxin–thioredoxin system

b.) Reduced thioredoxin cleaves the disulfide bonds of both phosphoribulokinase and CP12, releasing glyceraldehyde-3-phosphate dehydrogenase and phosphoribulokinase in the catalytically active conformations

c.) Oxidised thioredoxin cleaves the disulfide bonds of both phosphoglyceratekinase and CP12, releasing glyceraldehyde-3-phosphate dehydrogenase and phosphoglyceratekinase in the catalytically active conformations

d.) thioredoxin system oxidised the disulfide bonds and reduces the assembly of between chloroplast enzymes and CP12 and converted into the catalytically active conformations
