Host component of viral envelope is mostly

Options

A. Lipids
B. Carbohydrates
C. Lipids and proteins
D. Lipids and carbohydrates.

Answer

To answer the question "Host component of viral envelope is mostly," we need to analyze the components of a viral envelope and determine which parts are derived from the host.

### Step-by-Step Solution:

1. **Understanding the Viral Envelope**:
- The viral envelope is an outer layer that surrounds some viruses. It is derived from the host cell's membrane when the virus buds off from the host cell.

2. **Components of the Viral Envelope**:
- The viral envelope primarily consists of lipids and proteins. The lipids are typically phospholipids that come from the host cell membrane, while the proteins can be viral proteins that are inserted into the envelope.

3. **Host-Derived Components**:
- The lipids in the viral envelope are predominantly derived from the host cell. Additionally, carbohydrates may also be present, often attached to the proteins as glycoproteins.

4. **Analyzing the Options**:
- The options provided are:
- A) Lipid
- B) Carbohydrate
- C) Lipid and Protein
- D) Lipid and Carbohydrate
- Since the lipids are primarily from the host and carbohydrates can also be part of the glycoproteins, the most accurate answer would be "Lipid and Carbohydrate."

5. **Conclusion**:
- Therefore, the host component of the viral envelope is mostly "Lipid and Carbohydrate."

### Final Answer:
The host component of the viral envelope is mostly **Lipid and Carbohydrate**.
