Question

Assertion : The primary `CO_(2)` acceptor in `C_(4)` pathway is 3-carbon molecule phosphoenol pyruvate (PEP).
Reason: The enzyme responsible for this fixation is PEP carboxylase or PEPcase.

Answer 1

Correct Answer - B
Primary acceptor of `CO_(2)` in `C_(4)` plants is phosphoenol pyruvic acid (PEP). Carboxylation is catalysed by enzyme PEP carboxylase (PEPcase). First stable product in `C_(4)` plant is OA A (oxaloacetic acid) a 4C compound
