Question

In which form the Molybdenum is absorbed?

• A. $M_o{O}_3^{-3}$
• B. $Mo{O}_2^{+2}$
• C. $Mo{O}_4^{-4}$
• D. $Mo{O}_3^{-4}$

Answer 1

The correct option is C $Mo{O}_4^{-4}$

Molybdenum (Mo) is essential for both plants and animals. Within the plant, Mo is primarily used in the production of “molybdoenzymes” that regulate various plant functions. The most well known of these Mo-containing enzymes regulate nitrogen (N) nutrition.

In non-legumes, Mo-enzymes regulate the conversion of nitrate into proteins (nitrate reductase).Plants absorb molybdenum in the form of molybdate ions MoO₄( ^2- ).

It is a component of several enzymes, including nitrogenase and nitrate reductase involved in nitrogen metabolism. Molybdenum is absorbed in the form of molybdate ions $\left(Mo{O}_2^{+2}\right).$
