Question
First transistory chemical formed by reaction between CO2 and RUBP is
PGA
PGAL/ GAP
dihydroxy acetone phosphate
2 carboxy, 3-keto, 1-5 biphosphoribotol
Solution
D.
2 carboxy, 3-keto, 1-5 biphosphoribotol
During first phase, also known as carboxylation, of Calvin cycle RUBP or Ribulose-1, 5-biphosphate combine with CO2 in the presence of RUBP carboxylase or rubisco. It produces a transient intermediate compound 2 carboxy, 3-keto, 1-5 biphosphoribotol.
