Select the incorrectly matched pair with regard to the C4​ cycle. (1) Primary CO2​ fixation product - PGA (2) Site of initial carboxylation - Mesophyll cells (3) Primary CO2​ acceptor - PEP (4) C4​ plant - Maize (5) Location of enzyme RuBisCO - Bundle sheath cells

Answer: (1) Primary CO2​ fixation product – PGA

The primary CO2 fixation product in C4 plants is oxaloacetic acid, which is converted to malic acid or aspartic acid that is transported to the bundle sheath cells where the acid is decarboxylated and the CO2 thus released enters the Calvin cycle.
