State whether the following statements are true or false. In the sodium-potassium pump, sodium is transported out of the cell and potassium is transported into the cell as ATP is broken by a membrane protein.

Answer

To determine whether the statement about the sodium-potassium pump is true or false, we can analyze the components of the statement step by step.

### Step-by-Step Solution:

1. **Understanding the Sodium-Potassium Pump**:
- The sodium-potassium pump is a type of active transport mechanism found in the plasma membrane of cells. It is crucial for maintaining the electrochemical gradient across the cell membrane.

2. **Function of the Pump**:
- The pump works by moving sodium (Na⁺) ions out of the cell and potassium (K⁺) ions into the cell. This process is essential for various cellular functions, including nerve impulse transmission and muscle contraction.

3. **Role of ATP**:
- The sodium-potassium pump requires energy to function, which it obtains from the hydrolysis of ATP (adenosine triphosphate). When ATP is broken down, it releases energy that powers the pump.

4. **Mechanism of Action**:
- The pump typically transports three sodium ions out of the cell for every two potassium ions it brings in. This activity is mediated by a specific membrane protein that acts as an enzyme.

5. **Conclusion**:
- Since the statement accurately describes the process of sodium being transported out of the cell and potassium being transported into the cell, along with the involvement of ATP and a membrane protein, we conclude that the statement is true.

### Final Answer:
The statement is **True**.
