Regeneration of 6 RuBP in C₃ cycle requires

Question

Regeneration of 6 RuBP in C₃ cycle requires (A) 1 ATP (B) 6 ATP (C) 1 ATP and 1 NADPH+H+ (D) 3 ATP and 2 NADPH+H+

Tardigrade Admin · Accepted Answer

Regeneration is the step in which Ribulose-5 Phosphate takes phosphate from ATP to form Ribulose-1,5 Biphosphate. For fixation of 6 CO2 through Calvin cycle 6 ATP is consumed in regeneration step.
