Which of the following statement is correctly paired?
Options
- 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.
