Consider the following statement:
(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.
- ABoth (A) and (B) are true.
- B(A) is true but (B) is false.
- CBoth (A) and (B) are false.
- D(A) is false but (B) is true.
Solution & Step-by-step Explanation
- (A) is true: Prosthetic groups are organic compounds/metal ions distinguished from other cofactors in that they are tightly bound to the apoenzyme.
(B) is false: The complete active enzyme is called the holoenzyme. The protein part alone is called the apoenzyme.
(B) is false: The complete active enzyme is called the holoenzyme. The protein part alone is called the apoenzyme.
