Option (4) Phosphoenol pyruvate is correct.
This is because – PEP (Phosphoenol pyruvate) is the primary CO2 acceptor in C4 or Hatch and Slack pathway.
In Hatch and Slack pathway, the primary CO2 acceptor is
(1) Rubisco
(2) Oxaloacetic acid
(3) Phosphoglyceric acid
(4) Phosphoenol pyruvate
(1) Rubisco
(2) Oxaloacetic acid
(3) Phosphoglyceric acid
(4) Phosphoenol pyruvate
