Question: Identify the wrong match. 

(a) MO - Nitrogen metabolism 

(b) B - Carbohydrate translocation 

(c) Zn - Auxin synthesis 

(d) Fe - Splitting of water

Answer:

wrong match option: (d) Fe - Splitting of water

Explanation:

Option (a):

MO - nitrogen metabolism:

The molybdenum nitrogenase is responsible for most biological nitrogen fixation, a prokaryotic metabolic process that determines the global biogeochemical cycles of nitrogen and carbon. 

Option (b):

B - Carbohydrate translocation:

Boron is necessary for the translocation of sugar (carbohydrates) in plants. 

Option (c):

Zn - Auxin synthesis:

Auxin is a growth hormone which is synthesized by tryptophan as a precursor by tryptophan-dependent auxin biosynthesis pathway. Zinc helps in the biosynthesis of auxin and its oxidative attack by free radical. It suppresses the production of oxygen during the synthesis of auxin and also acts as a coenzyme and activates the enzyme for auxin formation.

Option (d):

Fe - Splitting of water:

The enzyme has four Mn ions. Light energized  Mn and removes electrons from OH component of water forming oxygen. So, the essential element required for water splitting in photosynthesis leading to release of oxygen is Mn.

Hence, the wrong match is (d) "Fe - Splitting of water".
