Question
The two subunits of ribosome remain united at a critical ion level of
Options
A.copper
B.manganese
C.magnesium
D.calainm
Solution
Magnesium is constituent of chlorophyll, middle lamella, and connected with phosphate transfer in respiration, binding of ribosomes and DNA and RNA synthesis. Manganese activates en zymes of respiration, photosynthesis and nitrogen metabolism performin oxidation, reduction, decarboxylation, photolysis of water etc. Copper is activator of plastocyanin, cytochrome oxidase, RuBP carboxylase and many other enzymes. It functions in electron transfer, mainte nance of cardohydrate/nitrogen balance, chlorophyll synthesis etc.
Calcium is constituent of middle lamella, activator of enzymes connected with chromosome formation and many aspects of metabolism.
