Vedclass · Answer

(A) $Cu$ (Copper) acts as a component of plastocyanin,which is involved in electron transport between $PS II$ and $PS I$,and in cytochrome oxidase for mitochondrial respiration.$Mn$ (Manganese) is essential for the photolysis of water in photosynthesis and acts as an activator for many enzymes involved in respiration and photosynthesis.$Fe$ (Iron) is a crucial component of cytochromes and ferredoxin,which are vital for electron transfer in both photosynthetic and mitochondrial electron transport chains.Therefore,the group $Cu, Mn, Fe$ is most critical for these processes.

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?
