ATP Structure and Function Quiz

What does ATP stand for?

• Adenosine triphosphate

• Adenosine diphosphate

• Adenosine tetraphosphate

• Adenosine monophosphate

Which of the following best describes the function of ATP in the body?

• It is the body’s energy currency.

• It is a structural protein.

• It is a type of enzyme.

• It is a waste product.

What are the components of ATP?

• Adenosine and 3 phosphate groups

• Adenosine and 2 phosphate groups

• Adenosine and 1 phosphate group

• Adenosine and 4 phosphate groups

What happens when one phosphate group breaks off from ATP?

• Energy is released.

• Oxygen is released.

• Glucose is produced.

• Water is formed.

What is the correct equation for the breakdown of ATP?

• ATP → ADP + Pi + energy

• ATP → AMP + Pi + energy

• ATP → ADP + glucose + energy

• ATP → AMP + ADP + energy

What is the role of the energy released from ATP?

• It powers biological work like muscle contraction.

• It is stored as fat.

• It is used to produce DNA.

• It is used to make proteins.

What is ADP?

• A by-product that results when ATP loses one phosphate group

• A molecule that stores more energy than ATP

• A type of sugar

• A type of enzyme

Why is ATP referred to as the "energy currency" of the cell?

• Because it provides energy for biological work, including muscle contraction

• Because it is made of sugar

• Because it is found only in the liver

• Because it stores genetic information

What does the diagram illustrate about ATP and energy release?

• ATP loses a phosphate group, releasing energy for muscle contraction.

• ATP gains a phosphate group, storing energy.

• ATP is converted into glucose.

• ATP is used to make proteins.

How long are ATP stores in muscles sufficient to support exercise?

• 1-2 seconds

• 10-15 seconds

• 1-2 minutes

• 1-2 hours
