ATP and Its Role in Cellular Processes

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

• Because it is a structural component of cell membranes.

• Because it is used to store genetic information.

• Because it provides energy for many cellular processes.

• Because it is involved in cell signaling.

Which of the following is NOT a component of ATP?

• Three phosphates

• Deoxyribose

• Ribose

• Adenine

What is the full name of ATP?

• Adenosine diphosphate

• Adenine diphosphate

• Adenosine triphosphate

• Adenine triphosphate

Which process does NOT involve oxygen in the generation of ATP?

• Aerobic respiration

• Anaerobic respiration

• Fermentation

• Photosynthesis

During cellular respiration, what do animals break down to produce ATP?

• Glucose

• Proteins

• Nucleic acids

• Lipids

What happens to ATP when it is hydrolyzed?

• It releases energy and loses a phosphate group.

• It gains a phosphate group.

• It forms a strong bond with water.

• It becomes more stable.

What is the term used when a phosphate from ATP is transferred to another molecule?

• Reduction

• Oxidation

• Hydrolysis

• Phosphorylation

What analogy is used to explain the energy release from ATP?

• A charged battery

• A stretched rubber band

• A flowing river

• A compressed spring

Where in the ATP molecule is the most energy stored?

• the bonds between the phosphate groups

• the bond holding the adenosine to the first phosphate group

• the bond between the two cyclic structures

• there is no energy stored in ATP

Free energy is released from ATP when

• a phosphate group is added

• adenine bonds to ribose

• ATP is exposed to sunlight

• a phosphate group is removed
