In Hatch and Slack pathway, the primary CO ₂ acceptor is

Options

  1. Aoxaloacetic acid
  2. Bphosphoglyceric acid
  3. Cphosphoenol pyruvate
  4. DRuBisCO

Correct answer

C. phosphoenol pyruvate

Step-by-step solution

In Hatch and Slack pathway, the primary CO ₂ acceptor is phosphoenol pyruvate. This occurs in C ₄ -plants. Phosphoenol pyruvate, a 3 -carbon compound, accepts CO ₂ and forms oxaloacetic acid which is a 4-carbon compound.
