While not even nearly all co-factors are minerals, some minerals are indeed cofactors; such as Iron in Haemoglobin.
Calcium

Metals ions are frequently cofactors of proteins.
These are Ribosomes.
Cofactors are nonprotein additions that are needed for enzyme activity. Cofactors are derived from vitamins and minerals.

coenzyme CORRECTION the above answer is wrong the correct answer is cofactors.
Calcium

Metals ions are frequently cofactors of proteins.
These are Ribosomes.
Cofactors
No, some enzymes do not need any additional components (cofactors or coenzymes) to show full activity.
I think you want cofactors as an answer.
