Q. Minerals involved in carbohydrate translocation, maintaining ribosome structure and activation of nitrogenase are respectively :

(a) Mn, B, Ca

(b) Ca, Mg, Mo

(c) B, Mn, Mo

(d) B, Mg, Mo

Solution :

Correct option : D Boron is necessary for the translocation of sugar (carbohydrates) in plants.
Magnesium ions (and other cations) play an important role in maintaining the structure of the ribosome. Nitrogenase is the Molybdenum dependent enzyme.
