Question

In $C_4$ plant PEPcase enzyme involve in :-

• A. Carboxylation
• B. Decarboxylation
• C. Oxidation
• D. Oxidative decarboxylation

Answer 1

The correct option is A Carboxylation

• Primary carboxylating enzyme, PEPcase in C4 plants is found in cytoplasm of mesophyll cells.
  
• Phosphoenolpyruvate carboxylase (PEPcase) catalyzes the fixation of carbon dioxide with phosphoenolpyruvate to produce oxaloacetate and inorganic phosphate.
  

So, the correct option is 'Carboxylation'.
