Which element generally activates the carboxylase enzyme?
1 Mo
2 \(\mathrm{Mn}\)
3 \(\mathrm{Mg}\)
4 \(\mathrm{Zn}\)
Explanation:
\(\mathrm{Mg}^{2+}\) is an activator for both ribulose bisphosphate carboxylaseoxygenase and phosphoenol pyruvate carboxylase, both of which are critical enzymes in photosynthetic carbon fixation.

The element involved in splitting of water is
1 \(\mathrm{Mn}\)
2 \(\mathrm{Ca}\)
3 \(\mathrm{Cl}\)
4 All of them
Explanation:
\(\mathrm{Mn}, \mathrm{Cl}\) and \(\mathrm{Ca}\) all of them are involved in splitting of water in plants. A calcium ion helps to push manganese up to a high enough oxidation state to enable plants to split water using sunlight.

Which of the following is true about iron?
1 It is a constituent of cytochrome.
2 It activates catalase enzyme.
3 It is essential for the formation of thiamine.
4 1 and 2
Explanation:
Iron \((\mathrm{Fe})\) is an important constituent of proteins involved in the transfer of electrons like ferredoxin and cytochromes. Iron also activates catalase enzyme, and is essential for the formation of chlorophyll.
