The enzyme required for carboxylation in the Calvin cycle is :NEET 2026 (Cancelled)
Options:
Answer:
C
Solution:
The Calvin cycle is the primary pathway for carbon fixation in plants.
The first step of the Calvin cycle is carboxylation, where carbon dioxide is added to a five-carbon acceptor molecule, Ribulose-1,5-bisphosphate (RuBP).
This reaction is catalyzed by the enzyme Ribulose bisphosphate carboxylase-oxygenase, commonly known as RuBisCO.
Hexokinase is an enzyme involved in glycolysis.
PEP carboxylase is the primary carboxylating enzyme in the C4 pathway.
Carboxypeptidase is a proteolytic enzyme involved in digestion.
Answer: RuBP carboxylase – oxygenase
