Enzymes not found in:

Options

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

Answer

To solve the question of where enzymes are not found, we can follow these steps:

### Step 1: Understand what enzymes are
Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are typically proteins and are crucial for various metabolic processes.

### Step 2: Analyze the options given
We have four options:
- A. Fungi
- B. Algae
- C. Viruses
- D. Cyanobacteria

### Step 3: Determine the nature of each option
- **Fungi**: These are multicellular or unicellular organisms that have cells and thus contain enzymes.
- **Algae**: These are also living organisms, primarily aquatic, and contain cells that produce enzymes.
- **Viruses**: Viruses are not considered living organisms as they do not have cellular structures. They cannot carry out metabolic processes on their own and do not contain enzymes.
- **Cyanobacteria**: These are photosynthetic bacteria that are unicellular and have cells, therefore they also contain enzymes.

### Step 4: Identify the option without enzymes
From the analysis, we can see that fungi, algae, and cyanobacteria are all living organisms that contain enzymes. However, viruses do not have cellular structures and therefore do not contain enzymes.

### Conclusion
The answer to the question "Enzymes not found in:" is **C. Viruses**.
