- AZn^{+2}& - It is an activator of nitrogenase during nitrogen fixation.
- BMo - Activator of alcohol dehydrogenase
- CMg^{+2}& - Activator of& phosphoenol pyruvate carboxylase.
- DCu -& Activator of RuBisCO
Correct answer
C. Mg^{+2}& - Activator of& phosphoenol pyruvate carboxylase.
Step-by-step solution
Mg^{2+} is an activator for both ribulose bisphosphate carboxylaseoxygenase and phosphoenol pyruvate carboxylase, both of which are critical enzymes in photosynthetic carbon fixation; Zn^{2+} is an activator of alcohol dehydrogenase and Mo of nitrogenase during nitrogen metabolism.
