Ribozymes are…………...that behave like enzymes

Options

A. Proteins
B. Ribonucleic acids
C. Oligosaccharide
D. Simple lipids

Answer

### Step-by-Step Solution:

1. **Understanding Ribozymes**: Ribozymes are a type of RNA molecule that can catalyze biochemical reactions, similar to the way that enzymes, which are typically proteins, do.

2. **Identifying the Options**: The question provides four options: proteins, ribonucleosides, oligosaccharides, and simple lipids. We need to determine which of these behaves like an enzyme.

3. **Analyzing Each Option**:
- **Proteins**: These are traditional enzymes but do not fit the definition of ribozymes.
- **Ribonucleosides**: These are building blocks of RNA but do not function as enzymes.
- **Oligosaccharides**: These are short chains of sugar molecules and do not act as enzymes.
- **Simple Lipids**: These are fats and oils and do not have enzymatic activity.

4. **Conclusion**: The only option that fits the description of ribozymes, which are RNA molecules that behave like enzymes, is **RNA**. Thus, ribozymes are RNA that behave like enzymes.

5. **Final Answer**: Ribozymes are **RNA** that behave like enzymes.
