Proteins those can be easily extracted from the plasma membrane, are :-

Options

A. Transmembrane
B. Integral
C. Peripheral
D. Intrinsic

Answer

To answer the question regarding which proteins can be easily extracted from the plasma membrane, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Plasma Membrane Proteins**:
- The plasma membrane is composed of various proteins that can be classified based on their extraction ease.

2. **Classification of Proteins**:
- Proteins associated with the plasma membrane are classified into two main categories: **Extrinsic (Peripheral) Proteins** and **Intrinsic (Integral) Proteins**.

3. **Extrinsic (Peripheral) Proteins**:
- Extrinsic proteins, also known as peripheral proteins, are located on the surface of the plasma membrane.
- They are loosely attached and can be easily extracted using mild treatments.

4. **Intrinsic (Integral) Proteins**:
- Intrinsic proteins, or integral proteins, are embedded within the lipid bilayer of the membrane.
- They are more difficult to extract because they span the membrane and require harsher methods for removal.

5. **Conclusion**:
- Based on the classification, the proteins that can be easily extracted from the plasma membrane are the **Extrinsic (Peripheral) Proteins**.

### Final Answer:
The proteins that can be easily extracted from the plasma membrane are **Extrinsic (Peripheral) Proteins**.
