Options:
Answer:
D
Solution:
In C4plants, initial fIxation of carbon dioxide occurs in mesophyll cells. The primary acceptor of CO2is phosphoenol pyruvate or PEP. It combines with carbon dioxide in the presence of PEP carboxylase or Pepcase to form oxaloacetate.
C4plants are more efficient in picking up CO2even when it is found in low concentration because of the high affinity of PEP carboxylcase.
