In what manner carrier proteins are different from ion channels?

Explanation

### Step-by-Step Solution:

1. **Definition of Carrier Proteins and Ion Channels**:
- Carrier proteins and ion channels are both integral membrane proteins that facilitate the transport of substances across the cell membrane. However, they operate through different mechanisms.

2. **Structure**:
- Carrier proteins do not have pores. Instead, they undergo conformational changes to transport molecules.
- In contrast, ion channels have specific pores that allow ions to pass through the membrane directly.
