Vedclass · Answer

(B) In the Calvin cycle ($C_3$ cycle),the enzyme phosphoketopentose epimerase (also known as ribulose-phosphate $3$-epimerase) catalyzes the reversible interconversion of xylulose-$5$-phosphate and ribulose-$5$-phosphate.This step is crucial for the regeneration phase of the Calvin cycle,where ribulose-$5$-phosphate is subsequently phosphorylated by phosphoribulokinase to regenerate ribulose-$1,5$-bisphosphate $(RuBP)$,the primary $CO_2$ acceptor.

In $C_3$ plants,phosphoketopentose epimerase is required for converting
