MCQ
In dark reaction, regeneration of $RuBP$ needs
  • A
    $2$ molecule of $ATP$
  • ✓
    $1$ molecule of $ATP$
  • C
    $3$ molecule of $ATP$
  • D
    $4$ molecule of $ATP$
✓

Answer

Correct option: B.
$1$ molecule of $ATP$
b
The Calvin cycle proceeds in three stages $(1)$ carboxylation, during which $C O_{2}$ combines with ribulose $1,5$ bisphosphate; $(2)$ reduction, during which carbohydrate are formed at the expense of the photochemically made $ATP$ and $NADPH$; and $(3)$ regeneration during, $C O_{2}$ acceptor is ribulose $1,5$ -bisphosphate is formed again so that the cycle continues. Regeneration of the $C O_{2}$ acceptor molecule, RuBP is crucial if the cycle is to continue uninterrupted. The regeneration steps require one $ATP$ for phosphorylation to form $RuBP$
