True or false: The integral proteins are partially or totally buried in the membrane.

Answer

To determine whether the statement "The integral proteins are partially or totally buried in the membrane" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Cell Membrane Composition**: The cell membrane is primarily composed of a lipid bilayer and proteins. The lipid bilayer forms the basic structure of the membrane.

2. **Identify Types of Proteins**: There are two main types of proteins associated with the cell membrane:
- **Integral Proteins**: These proteins are embedded within the lipid bilayer. They can either be partially or completely buried in the membrane.
- **Peripheral Proteins**: These proteins are not embedded in the lipid bilayer; instead, they are attached to the surface of the membrane.

3. **Analyze the Statement**: The statement in question is about integral proteins being "partially or totally buried" in the membrane. Since integral proteins are defined by their embedding within the lipid bilayer, this statement aligns with the definition of integral proteins.

4. **Conclusion**: Since integral proteins can indeed be partially or completely embedded in the membrane, the statement is **true**.

### Final Answer:
**True**: The integral proteins are partially or totally buried in the membrane.
