Question

PEP is primary CO2 acceptor in A. C3 plants B. C4 plants C. C2 plants D.Both C3 and C4 plants​

Answer 1

Answer:

C4 is correct answer

Explanation:

PEP is the 3C compound and acts as the primary CO2 acceptor in the mesophyll cells of C4 plants, leading to the formation of OAA, C4 acid. The enzyme PEP carboxylase or PEPcase catalyses this reaction. RuBP (5C) acts as the primary CO2 acceptor in C3 plants, leading to the formation of 2 molecules of 3-PGA (C3 acid). The enzyme RuBisCO catalyses the reaction.
