A) Ribozyme - Proteinaceous in nature
B) Apoenzyme - The protein part of enzyme
C) Co-enzyme - Loosely attached organic co-factor of holoenzyme
D) Co-factors - Non-protein part of holoenzyme
Correct Answer: A
Solution :
[a] Ribozymes (ribonucleic acid enzymes) are also called catalytic RNA. They are RNA molecules capable of catalysing specific biochemical reactions, similar to the actof protein enzymes. Ribozyme, discovered in 1982, demonstrated that RNA can be both genetic material (like DNA) and a biological catalyst (like protein enzymes). Examples of ribozymes include the hammerhead ribozyme, the VS ribozyme, Leadzyme and the hairpin ribozyme.
