$Mg^{++}$

Vedclass · Answer

(A) In biological systems,$ATP$ (Adenosine Triphosphate) exists primarily as a complex with magnesium ions $(Mg^{++})$. This is because the phosphate groups of $ATP$ are negatively charged and require a divalent cation like $Mg^{++}$ to stabilize the molecule. Many enzymes that utilize $ATP$ in the plasma membrane,such as $Na^+/K^+$-ATPase,require $Mg^{++}$ as an essential cofactor for their catalytic activity. Therefore,$Mg^{++}$ is the activator that remains associated with $ATP$ to facilitate its hydrolysis and energy release.

Which one of the following activators remains attached to $ATP$ in the plasma membrane?
