ATP and Energy Conversion Quiz

What is the primary role of ATP in cells?

• To transport oxygen

• To carry and store energy for cell functions

• To act as a structural component

• To store genetic information

Which components make up the structure of ATP?

• Adenine, ribose, and three phosphate groups

• Thymine, deoxyribose, and one phosphate group

• Guanine, deoxyribose, and two phosphate groups

• Cytosine, ribose, and four phosphate groups

Why is ATP considered unstable compared to ADP?

• It has fewer phosphate groups

• It has more phosphate groups

• It lacks a sugar component

• It has a stronger nitrogen base

What happens when a phosphate group is removed from ATP?

• The molecule becomes less stable

• The molecule becomes more stable

• Energy is released

• Energy is absorbed

What is the role of ATP synthase in ATP production?

• It breaks down ATP into ADP

• It facilitates the addition of a phosphate group to ADP

• It removes energy from ATP

• It converts glucose directly into ATP

Why is an enzyme necessary for the conversion of ADP to ATP?

• The reaction is spontaneous

• The reaction is non-spontaneous and requires facilitation

• The reaction releases energy

• The reaction does not involve any energy change

Which macromolecule is the most efficient source of energy for ATP production?

• Carbohydrates

• Lipids

• Proteins

• Nucleic acids

How many ATP molecules can be produced from one glucose molecule if the process is perfectly efficient?

• 24 ATP

• 48 ATP

• 12 ATP

• 36 ATP

Which macromolecule stores the most energy per gram?

• Nucleic acids

• Lipids

• Carbohydrates

• Proteins

Why are proteins the least likely to be used for ATP production?

• They are not present in the body

• They are the most unstable macromolecules

• They are primarily used for other cellular functions

• They store the least energy
