$Cu, Mn$ and $Fe$

Vedclass · Answer

(A) The elements $Cu$ (Copper),$Mn$ (Manganese),and $Fe$ (Iron) are essential components of various electron transport chain complexes.$Fe$ is a critical component of cytochromes and ferredoxin,which are involved in both photosynthetic and mitochondrial electron transport.$Cu$ is a component of plastocyanin in photosynthesis and cytochrome $c$ oxidase in the mitochondrial electron transport chain.$Mn$ is essential for the water-splitting complex in photosystem $II$ during photosynthesis and acts as a cofactor for several enzymes in respiration.Therefore,the deficiency of these three elements significantly impacts both photosynthetic and mitochondrial electron transport processes.

$(a)$ Iron	$(i)$ Photolysis of water
$(b)$ Zinc	$(ii)$ Pollen germination
$(c)$ Boron	$(iii)$ Required for chlorophyll biosynthesis
$(d)$ Manganese	$(iv)$ $IAA$ biosynthesis

The deficiencies of micronutrients not only affect the growth of plants but also vital functions,such as photosynthetic and mitochondrial electron flow. Among the list given below,which group of three elements shall affect most,both photosynthetic and mitochondrial electron transport?
