Which is the role of the enzyme Rubisco?
zalisa [80]

Answer:

Option D, Condensation of ribulose 1,5 bisphosphate with carbon dioxide and splitting of a six-carbon product during the Calvin cycle.

Explanation:

The enzyme Ribulose 1,5- bisphosphate carboxylase/oxygenase act as a catalyst in the reaction where CO2 attaches to ribulose 1,5-bisphosphate. In the end of this process, an unstable six carbon compound is formed.

Ribulose 1,5- bisphosphate is a molecule containing 5 - carbon molecule an when it combines it with CO2 during the Calvin cycle it splits into two molecules of 3-phosphoglyceric acid (3-PGA) which contains three carbon. This reaction is catalysed by Ribulose 1,5- bisphosphate carboxylase/oxygenase enzyme.

Hence option D is correct.
