Solution

The correct option is C Mg
Glycolysis is the first step of respiration which takes place in 10 steps and each step occurs in the presence of a specific enzyme. Various enzymes require divalent magnesium ions as cofactor. The first, third, sixth, eighth, and ninth steps require magnesium ions as an activator for the actual enzymes to function.
Thus, the correct answer is option C.
