How is energy released from ATP?

• When a phosphate group is removed.

• When ATP is hydrolyzed to ADP and glucose.

• When ATP is exposed to high temperatures.

• When ATP is combined with oxygen.

What happens to ATP when it loses a phosphate group?

• It becomes ADP.

• It becomes AMP.

• It is converted to glucose.

• It is transformed into creatine phosphate.

What is the main function of ATP in cells?

• To provide energy for cellular processes.

• To store genetic information.

• To transport oxygen in the blood.

• To synthesize proteins.

What is the role of phosphate groups in ATP?

• Phosphate groups store and release energy when added or removed.

• Phosphate groups are responsible for the structural integrity of ATP.

• Phosphate groups help in the synthesis of proteins.

• Phosphate groups are involved in the transport of oxygen in the blood.
