When Apoenzyme Is Separated from Its Metal?

So, the correct answer is 'decreased'.

What happens when apoenzyme is separated from cofactor?

If the cofactor is removed from a complete enzyme (holoenzyme), the protein component (apoenzyme) no longer has catalytic activity. ... A cofactor that is bound loosely to the apoenzyme and can be readily separated from it is called a coenzyme.

What will happen to enzyme when apoenzyme?

After binding to a cofactor, apoenzyme forms a holoenzyme which is an active enzyme and can perform the catalytic activity. Most cofactors are bound tightly to a coenzyme but they are not bound by a covalent bond.
