A) RuBP carboxylase
B) hydrogenase
C) PEP carboxylase
D) reductase
Correct Answer: A
Solution :
| [A] In C4 plants, initial fixation of CO2 takes place in the mesophyll cells. The primary acceptor of CO2 is phosphoenol pyruvate (=PEP) which combines with CO2 in the presence of PEP carboxylase to form oxaloacetic acid. RuBP carboxylase is the primary CO2 acceptor in C3 plants. Hydrogenase enzyme is common in micro organisms. It takes up or evolves gaseous O2. Reductase or dehydrogenase enzyme catalyzes the dehydrogenation or removal of hydrogen atoms (or electrons). |
