A) formation of bundle sheath cells
B) formation of oxaloacetate by carboxylation of phosphoenol pyruvate (PEP) in the mesophyll cells
C) formation of phosphoglyceric acid in mesophyll cells
D) formation of oxaloacetate by carboxylation of phosphoenol pyruvate (PEP) in bundle sheath cells
Correct Answer: B
Solution :
Hatch and Slack cycle is present in \[{{C}_{4}}\] plants in which initial fixation of carbon dioxide \[(C{{O}_{2}})\] occurs in mesophyll cells phosphoenol pyruvate (PEP) is the primary acceptor of \[C{{O}_{2}}\] which combines to \[C{{O}_{2}}\] form four carbon compounds oxaloacetic acid as a result of carboxylation \[PEP+C{{O}_{2}}+{{H}_{2}}O\xrightarrow[\begin{smallmatrix} Carboxylase \\ Oxalso-\,acetic\,acid \end{smallmatrix}]{PEP}\]
