Enzymes are not found in

Options

A. Fungi
B. Cyanobacteria
C. Virus
D. Algae.

Answer

**Step-by-Step Solution:**

1. **Understanding Enzymes**: Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are crucial for various metabolic processes.

2. **Identifying the Options**: The question provides four options: fungi, cyanobacteria, virus, and algae. We need to determine which of these does not contain enzymes.

3. **Analyzing Each Option**:
- **Fungi**: Fungi are eukaryotic organisms that have complex cellular structures and possess various enzymes to aid in their metabolic processes.
- **Cyanobacteria**: Cyanobacteria are photosynthetic bacteria that also contain enzymes necessary for their metabolic functions.
- **Algae**: Algae are also eukaryotic organisms that perform photosynthesis and have enzymes for metabolism.
- **Virus**: Viruses are acellular entities that consist of nucleic acid (either DNA or RNA) surrounded by a protein coat. They do not possess cellular structures, such as ribosomes or a cell membrane, and they lack metabolic processes.

4. **Conclusion**: Since viruses do not have metabolism and do not contain enzymes, the correct answer to the question is "virus".

**Final Answer**: Enzymes are not found in viruses.
