Vedclass · Answer

(D) The $TCA$ cycle (also known as the Krebs cycle or Citric Acid cycle) involves several enzymes that require metal ion cofactors for their catalytic activity.Specifically,the carboxylase enzymes involved in the $TCA$ cycle,such as isocitrate dehydrogenase and $\alpha$-ketoglutarate dehydrogenase,utilize $Mn^{++}$ (manganous ions) as a crucial mineral activator to facilitate the decarboxylation reactions.Therefore,$Mn^{++}$ is the correct mineral activator.

The mineral activator required for the carboxylase enzymes of the $TCA$ cycle is
