Complete the analogy

Peroxidase : Fe 2+

Hexokinase : ?

(1) Ca2+

(2) Cu2+

(3) Mg2+

(4) Co2+

Answer:

(3) Mg2+

Explanation:

The Fe2+ given here for peroxidase is a co-factor necessary for the enzyme to function. Co factors like the divalent ions support the enzyme by either enhancing the function or helping with the enzyme substrate confirmations.

Similarly, Hexokinase is an enzyme used in the first step of glycolysis where glucose is converted to glucose-6- phosphate. This step uses ATP 's one phosphate group to add it to the glucose molecule phosphorylating it. So, we see a conversion of ATP to ADP. For this step to take place properly Mg2+ as a cofactor involves with the ATP preventing it from hydrolysis. This ensures an efficient phosphorylation.
