What molecule provides the chemical energy needed for a cell to do work?

• Glucose

• Ribose

• Adenosine triphosphate (ATP)

• Adenosine diphosphate (ADP)

What are the three components that make up ATP?

• Adenine, ribose sugar, and 2 phosphate groups

• Adenine, glucose, and 3 phosphate groups

• Adenine, ribose sugar, and 3 phosphate groups

• Glucose, ribose sugar, and 3 phosphate groups

What happens when the third phosphate is removed from ATP?

• ATP is converted into ADP, releasing energy

• ATP is converted into glucose, releasing energy

• ATP becomes more stable and stores more energy

• ATP is converted into ribose sugar, releasing energy
