Question

What are co-factors? Give an example. What will happen if the

co-factor is removed from the enzyme?

Answer 1

Cofactors are not proteins but rather help proteins, such as enzymes, although they can also help non-enzyme proteins as well. Examples of cofactors include metal ions like iron and zinc
If the cofactor is removed from a complete enzyme (holoenzyme), the protein component (apoenzyme) no longer has catalytic activity. ... Coenzymes take part in the catalyzed reaction, are modified during the reaction, and may require anotherenzyme-catalyzed reaction for restoration to their original state.
