Total questions: 27
Worksheet time: 14mins
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.
What is the relationship between ATP and ADP in terms of energy storage?
ADP stores more energy than ATP
ATP is the result of ADP losing one phosphate group
ATP and ADP have the same energy storage capacity
ATP stores energy in its high-energy phosphate bonds, while ADP is the result of ATP losing one phosphate group, releasing energy.
The energy we obtain from food can be used immediately for energy in the form of carbohydrates, fats, etc.
True
False
The nutrients we obtain from food must first be converted to ATP before it can be used as energy
True
False
The term "Synthesis" refers to:
The production of chemical compounds by a reaction from simpler compounds
The production of chemical compounds by a reaction from more complex compounds
The breakdown of chemical compounds by a reaction from simpler compounds
The breakdown of chemical compounds by a reaction from more complex compounds
The synthesis of something again
Synthesis
Resynthesis
Glycolysis
Glycogenolysis
Which enzyme is responsible for the breakdown of ATP to ADP?
Creatine Kinase
Lipases
ATPase
ATP synthase
When ATP is being broken down into ADP, the bond between phosphate molecules
Releases energy
Requires energy
Remains the same
Is enhanced (becomes stronger)
The energy that is released from the high-energy bond between the phosphate molecules within ATP is used for muscular contraction
True
False
The energy that is released from the high-energy bond between the phosphate molecules within ATP is used for muscular contraction
True
False
There are large ATP storage sites within skeletal muscle which is why ATP resynthesis does not need to occur until the lactic acid system becomes the predominant energy system being used
True
False
ATP storage is minimal which is why ATP must be resynthesized to enable us to continue exercising
True
False
Myosin heads use the breakdown of ATP to trigger the contraction process
True
False
ATP reattaches to the myosin head & this causes the "power stroke"
True
False
ATP reattaches to the myosin head & this causes the detachment of the cross bridge in preparation for the next phase where ATP is again broken down into ADP & Pi, thus causing the reattachment of the myosin head and the pulling of the actin filament further down the line which is known as the "ratchet mechanism"
True
False
