Activation of catalase enzyme, formation of chlorophyll, electron transfer are all associated with which of the following elements?
Open in App
Solution
The correct option is D Iron
Iron is obtained by plants as a ferrous ion. It is involved in activation of catalase enzyme, formation of chlorophyll & electron transfer proteins like ferredoxin & cytochromes.
Zinc is absorbed by plants as divalent cation. It is involved in activation of carboxylases and auxin synthesis.
Magnesium is absorbed by plants as divalent cation. It is involved in activation of enzymes of respiration, photosynthesis, DNA & RNA synthesis. It is a principle component of chlorophyll and it helps maintain ribosome structure.
Sulphur is absorbed by plants as sulphate ion. It is found in 2 amino acids- cysteine & methionine. It is a principle component of coenzymes, vitamins and ferredoxin.
