Question

Consider the following statements :
(A) Coenzyme or metal ion that is tightly bound to enzyme protein is called prosthetic group.
(B) A complete catalytic active enzyme with its bound prosthetic group is called apoenzyme
Select the correct option.
(1) Both (A) and (B) are true.
(2) (A) is true but (B) is false.
(3) Both (A) and (B) are false.
(4) (A) is false but (B) is true

Answer 1

Both (A) and (B) are false.

Step by step explanation:

• Coenzymes are molecules small in size. We can not catalyze a reaction on their own but can support enzymes in doing so.
• These are nonprotein molecules.
• Coenzymes, metal ions, and prothestic groups that are bound to enzyme protein are called cofactor.
• Prosthetic groups are closely linked to enzymes where metal ions and coenzymes are not closely linked to enzymes.

Hence, correct option - 3
