Consider the following statement :(A) Coenzyme or metal ion that is ti...
Statement (A): Coenzyme or metal ion that is tightly bound to enzyme protein is called prosthetic group.
Coenzymes and metal ions are essential cofactors required for the proper functioning of enzymes. Coenzymes are small, organic molecules that are loosely bound to the enzyme protein and are necessary for the enzyme's catalytic activity. In contrast, prosthetic groups are coenzymes or metal ions that are tightly bound to the enzyme protein. They are usually involved in the enzyme's active site and participate directly in the catalytic reaction. Therefore, statement (A) is correct.
Statement (B): A complete catalytic active enzyme with its bound prosthetic group is called apoenzyme.
Apoenzyme refers to an enzyme lacking its necessary cofactor or prosthetic group. In other words, it is the protein component of an enzyme without any bound cofactor or prosthetic group. The apoenzyme itself lacks catalytic activity and requires the presence of its cofactor or prosthetic group to become fully active. Therefore, statement (B) is incorrect as it defines an apoenzyme rather than an enzyme with its bound prosthetic group.
Conclusion:
Based on the explanations above, we can conclude that statement (A) is true, but statement (B) is false. Therefore, the correct option is (B): (A) is true, but (B) is false.
