Question:medium

24 PGAL molecules are formed in $C_3$ plant. Calculate the number of $CO_2$ used and the number of G3P used for regeneration of RUBP molecules?

Show Hint

Remember the ratio for gross PGAL production: For every 6 PGAL formed $\rightarrow$ 3 $CO_2$ in $\rightarrow$ 5 PGAL regenerate RuBP $\rightarrow$ 1 PGAL net gain.

  • 12 $CO_2$ & 24 G3P
  • 24 $CO_2$ & 48 G3P
  • 12 $CO_2$ & 20 G3P
  • 20 $CO_2$ & 12 G3P
