PEP is primary CO₂ acceptor in

1.  C₄ plants

2.  C₃ plants

3.  C₂ plants

4.  both C₃ and C₄ plants

The enzyme that is not found in a C₃ plant is

1.  RuBP carboxylase

2.  PEP carboxylase

3.  NADP reductase

4.  ATP synthase

The reaction that is responsible for the primary fixation of CO₂ is catalysed by

1.  RUBP carboxylase

2.  PEP carboxylase

3.  RuBP carboxylase and PEP carboxylase

4.  PGA synthase

When CO₂ is added to PEP, the first stable product synthesized is

1. pyruvate

2. glyceraldehyde-3-phosphate

3. phosphoglycerate

4. oxaloacetate
