Vedclass · Answer

(B) $Mg^{++}$ acts as a cofactor for many enzymes involved in phosphate group transfer and energy metabolism.$1$. $A$ (Pyruvate dehydrogenase) requires $Mg^{++}$ for the link reaction.$2$. $C$ (Hexokinase) requires $Mg^{++}$ for the phosphorylation of glucose in glycolysis.$3$. $D$ (Rubisco) requires $Mg^{++}$ for its catalytic activity in the Calvin cycle.$4$. $F$ ($PEP$ carboxylase) requires $Mg^{++}$ for the carboxylation step in $C_4$ photosynthesis.Therefore, the enzymes activated by $Mg^{++}$ are $A, F, C,$ and $D$.

Which of the following enzymes are activated in the presence of $Mg^{++}$?
$(A)$ Pyruvate dehydrogenase
$(B)$ $DNA$ polymerase
$(C)$ Hexokinase
$(D)$ Rubisco
$(E)$ Catalase
$(F)$ $PEP$ carboxylase
$(G)$ Amylase
Options:
$(a)$ $B, C, D, E$
