Multiple choice

Which of the following matchings is incorrect?

  1. Ribulose l,5-bisphosphate → 3-phosphoglycerate: Rubisco

  2. 3-Phospho glycerate → Glycerate 1,3-bisphosphate: Phosphoglycerate kinase

  3. Dihydroxy acetone phosphate → Fructose 1,6-bisphosphate: Aldolase

  4. Xylulose 5-phosphate → Ribulose 5-phosphate: ribose-5-phosphate isomerase

  5. Ribulose 5-phosphate → Ribulose 1,5,- bisphosphate: Phosphoribulokinase

D Correct answer
Explanation

This option is wrong because conversion of xylulose 5-phosphate to ribulose 5-phosphate is catalysed by ribulose-phosphate epimerase, whereas conversion of ribose 5-phosphate to ribulose 5-phosphate is catalysed by ribose-5-phosphate isomerise.
