What happens when energy is needed by the body?

• A phosphate group is added to ATP

• A phosphate group is removed from ATP

• ATP is converted into ADP

• ATP is stored for future use

What is released when ATP is split off?

• Oxygen

• Carbon dioxide

• Energy

• Water

What is the role of ATP in active transport mechanisms such as the sodium-potassium pump?

• ATP is used to change the shape of the channel allowing sodium ions to be pumped out of the cell.

• ATP directly transports sodium and potassium ions across the cell membrane without changing the channel shape.

• ATP provides energy for passive transport of ions against the concentration gradient.

• ATP is used to deactivate the sodium-potassium pump once the ions have been transported.
