NEET · BiologyMedium
In C4 plants, the primary carbon dioxide acceptor in the mesophyll cells is a three-carbon compound. What is this compound?
- A.
- B.
- C.
- D.
Show correct answer & step-by-step solution
Correct answer: B —
Solution
- C4 photosynthesis involves the Hatch-Slack pathway.
- The enzyme PEP carboxylase fixes atmospheric in mesophyll cells.
- The substrate for this carboxylation is the three-carbon molecule Phosphoenolpyruvate (PEP).
- Hence the answer is (B).
