AP Biology: Na K Pump

What is the mechanism of the Na K pump?

• The Na K pump transports sodium ions out of the cell and potassium ions into the cell without using ATP as an energy source.

• The Na K pump actively transports sodium ions out of the cell and potassium ions into the cell using ATP as an energy source.

• The Na K pump transports potassium ions out of the cell and sodium ions into the cell using ATP as an energy source.

• The Na K pump passively transports sodium ions out of the cell and potassium ions into the cell.

How does the Na K pump work?

• The Na K pump uses glucose to pump sodium ions out of the cell and potassium ions into the cell.

• The Na K pump uses ATP to pump sodium ions out of the cell and potassium ions into the cell.

• The Na K pump uses oxygen to pump sodium ions out of the cell and potassium ions into the cell.

• The Na K pump uses carbon dioxide to pump sodium ions out of the cell and potassium ions into the cell.

Describe the process of sodium (Na) and potassium (K) ion transport in the Na K pump.

• Passive transport through diffusion

• Facilitated transport through carrier proteins

• Active transport using ATP energy

• Active transport using glucose energy

What are the differences between the Na K pump and other ion pumps in the cell?

• The Na K pump is a passive transporter of sodium and potassium ions, while other ion pumps in the cell are active transporters.

• The Na K pump transports both sodium and potassium ions out of the cell, while other ion pumps in the cell transport only one type of ion.

• The Na K pump transports potassium ions out of the cell and sodium ions into the cell, while other ion pumps in the cell transport different ions and have different functions.

• The Na K pump actively transports sodium ions out of the cell and potassium ions into the cell, while other ion pumps in the cell transport different ions and have different functions.

Discuss the significance of the Na K pump in nerve cell function.

• The Na K pump is only found in muscle cells, not nerve cells.

• The Na K pump is essential for maintaining the resting membrane potential and generating action potentials in nerve cells.

• The Na K pump is not involved in maintaining the resting membrane potential in nerve cells.

• The Na K pump is responsible for transmitting signals between nerve cells.

Explain how the Na K pump contributes to the generation of action potentials.

• The Na K pump contributes to the generation of action potentials by maintaining the concentration gradients of Na+ and K+ ions across the cell membrane.

• The Na K pump generates the action potentials by creating a positive charge inside the cell.

• The Na K pump has no role in the generation of action potentials.

• The Na K pump generates the action potentials by directly releasing Na+ and K+ ions into the cell membrane.

What happens if the Na K pump fails to function properly?

• The malfunction of the Na K pump has no effect on cell function.

• The malfunction of the Na K pump can disrupt cell function and have various physiological effects.

• The Na K pump is responsible for regulating blood pressure.

• The Na K pump failure can lead to increased cell function.
