PEP is primary `CO_(2)` acceptor inA. `C_(4)` plantsB. `C_(3)` plantsC. `C_(2)` plantsD. both `C_(3)` and `C_(4)` plants. |

Answer» Correct Answer - A In `C_(4)` plants, initial fixation of `CO_(2)` or carboxylation occurs in mesophyll cells. The chloroplasts of mesophylls cells possess enzyme PEP carboxylase (or PEP cae) for initial fixation of `CO_(2)`. The primary acceptor of `CO_(2)` is phosphoenol pyruvate or PEP. It cobines with `CO_(2)` in the presence of PEP carboxylase (or PEP case) to form oxaloacetic acid or oxaloacetate (O A A). |
