Vedclass · Answer

(D) $Mg^{2+}$ (Magnesium ion) acts as an essential cofactor or activator for several key enzymes involved in photosynthesis.Specifically,it activates:$1.$ Ribulose bisphosphate carboxylase oxygenase (RuBisCO),which is the primary enzyme for carbon fixation in the Calvin cycle.$2.$ Phosphoenol pyruvate carboxylase (PEPCase),which is the primary enzyme for carbon fixation in $C_4$ plants.Therefore,both $III$ and $IV$ are correct.

$Mg^{2+}$ is an activator of:
$I.$ Alcohol dehydrogenase
$II.$ Nitrogenase
$III.$ Ribulose bisphosphate carboxylase oxygenase
$IV.$ Phosphoenol pyruvate carboxylase
Choose the correct option.
