Vedclass · Answer

(C) The given pathway represents the $C_4$ cycle (Hatch-Slack pathway). $A$ represents the primary fixation of $CO_2$ in the mesophyll cells,where $PEP$ (Phosphoenolpyruvate) combines with $CO_2$ to form a $C_4$ acid (Oxaloacetate). $B$ represents the decarboxylation step in the bundle sheath cells,where the $C_4$ acid releases $CO_2$ to enter the Calvin cycle and converts into a $C_3$ acid. $C$ represents the regeneration of $PEP$ from the $C_3$ acid in the mesophyll cells to continue the cycle. Therefore,the correct sequence is Fixation $\rightarrow$ Decarboxylation $\rightarrow$ Regeneration.
