3.3.4-3.3.5 - Gain & Loss of Phosphate to Adenosine | ATP Energy

What does ATP stand for?

• Adenosine Triphosphate

• Adenosine Pentaphosphate

• Adenosine Trisphosphate

• Adenosine Tetraphosphate

Describe the structure of adenosine triphosphate.

• Adenosine triphosphate consists of an adenosine molecule attached to three phosphate molecules.

• Adenosine triphosphate has a structure of adenosine linked to two phosphate molecules.

• Adenosine triphosphate is composed of four phosphate molecules.

• Adenosine triphosphate contains only one phosphate group attached to an adenosine molecules.

How is adenosine diphosphate formed?

• Energy bond between phosphates within ATP is broken down by the enzyme Creatine Kinase

• Energy bond between phosphates within ATP is broken down by the enzyme ATPase

• Energy bond between phosphates within ATP is broken down by the enzyme Lipases

• A phosphate group is added to ATP to produce ADP

Explain the process of phosphorylation of adenosine.

• Phosphorylation of adenosine is the addition of a phosphate group to the adenosine molecule

• Phosphorylation of adenosine results in the formation of a lipid molecule.

• Phosphorylation of adenosine is a spontaneous process that does not require any enzymes.

• Phosphorylation of adenosine involves the removal of a phosphate group from the adenosine molecule.

What is the role of enzymes in ATP synthesis?

• Enzymes inhibit the chemical reactions involved in ATP synthesis

• Enzymes have no role in ATP synthesis

• Enzymes catalyze (speed up) the chemical reactions involved in ATP synthesis

• Enzymes prolong the breakdown of ATP

What are the three phosphate groups in ATP connected by?

• high-energy bonds

• low-energy bonds

• covalent bonds

• ionic bonds

How does adenosine diphosphate differ from adenosine triphosphate?

• ADP has one phosphate group, while ATP has two phosphate groups.

• ADP has two phosphate groups, while ATP has three phosphate groups.

• ADP is a storage molecule, while ATP is a structural molecule.

• ADP is used in photosynthesis, while ATP is used in cellular respiration.

How does the addition of a phosphate group affect the energy stored in ATP?

• The addition of a phosphate group decreases the energy stored in ATP.

• The addition of a phosphate group converts ATP into ADP.

• The addition of a phosphate group increases the energy stored in ATP.

• The addition of a phosphate group has no effect on the energy stored in ATP.

What is the main function of ATP in cells?

• ATP helps in maintaining cell shape

• ATP is responsible for cell division

• ATP serves as the main energy currency in cells.

• ATP is the chemical messenger notifying the body that blood glucose is high and needs to be converted to glycogen

How does the breakdown of ATP release energy for cellular processes?

• ATP is broken down into ADP and phosphate, releasing energy.

• ATP is converted into glucose and oxygen, releasing energy.

• ATP is transformed into lipids and proteins, releasing energy.

• ATP is hydrolyzed into water and carbon dioxide, releasing energy.
