The 1 4 C label should be traced in 3PG carbon. Concept introduction: In green plants the 1 4 CO 2 enters with ribulose1,5-biphosphate. The entry of labeled 1 4 C in the system occurs as carboxylate of one of the molecules of 3-phosphogylcerate. Hence, the C1- of the phosphoglycerate is first labeled as 1 4 C-carbon. In the cycle, this molecule first gives glyceraldehyde-3-phosphate and then dihydroxyacetone phosphate which further combine to give fructsose-6-biphosphate. Pictorial representation: Ribulose-5-phosphate exists in isomeric form, where C-1 is labeled as C-14:

Interpretation Introduction

Interpretation:

The ¹⁴C label should be traced in 3PG carbon.

Concept introduction:

In green plants the ¹⁴CO₂ enters with ribulose1,5-biphosphate.

The entry of labeled ¹⁴C in the system occurs as carboxylate of one of the molecules of 3-phosphogylcerate.

Hence, the C1- of the phosphoglycerate is first labeled as ¹⁴C-carbon. In the cycle, this molecule first gives glyceraldehyde-3-phosphate and then dihydroxyacetone phosphate which further combine to give fructsose-6-biphosphate.
