Question: Consider the following statements: [NEET 5-5-2019]
[A] Coenzyme of 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.
Options:
A) Both [A] and [B] are false
B) [A] is false but [B] is true
C) Both [A] and [B] are true
D) [A] is true but [B] is false
Show Answer
Answer:
Correct Answer: D) [A] is true but [B] is false
Solution:
[A] is true because a coenzyme or metal ion that is tightly bound to an enzyme protein is indeed called a prosthetic group. [B] is false because a complete catalytically active enzyme with its bound prosthetic group is called a holoenzyme, not an apoenzyme. An apoenzyme is the protein part of an enzyme without its prosthetic group or cofactor.
