MCQ
Which of the following is present in Calvin cycle
- APhotophosphorylation
- BOxidative carboxylation
- ✓Reductive carboxylation
- DOxidative phosphorylation
✓
Answer
Correct option: C.
Reductive carboxylation
c
(c) Reductive carboxylation start with a $5$, carbon sugar ribulose -$5$ phosphate. $6 $ mol of this sugar react with $6$ mol of $ATP$ (produced in light reaction) to form $6$ mol of $RuBP$ and $6$ mol $ADP$
(c) Reductive carboxylation start with a $5$, carbon sugar ribulose -$5$ phosphate. $6 $ mol of this sugar react with $6$ mol of $ATP$ (produced in light reaction) to form $6$ mol of $RuBP$ and $6$ mol $ADP$
Ribulose - $5$ phosphate $\xrightarrow{{{\text{ Phosphopentokinase}}}}$ Ribulose $1-5 $ biphosphate + $6ADP$
