Cellular Respiration Questions and
Answers Already Graded A
How is water formed during cellular respiration?
✔✔When oxygen combines with electrons and hydrogen ions.
What is the significance of Coenzyme A in respiration?
✔✔It delivers acetyl groups to the citric acid cycle.
What happens to ATP after it is used by the cell?
✔✔It becomes ADP and can be recycled to form ATP again.
What part of respiration is directly responsible for making water?
✔✔The electron transport chain.
What type of bond in ATP stores the most energy?
✔✔The bond between the second and third phosphate groups.
1
, What is the connection between cellular respiration and body temperature?
✔✔Cellular respiration releases heat that helps maintain body temperature.
Can fats and proteins be used in cellular respiration?
✔✔Yes, they can be broken down into molecules that enter the respiration pathway.
Why is cellular respiration considered a redox reaction?
✔✔Because it involves the transfer of electrons from glucose to oxygen.
How many molecules of CO₂ are released per glucose during respiration?
✔✔Six.
What is the purpose of breaking down glucose slowly in steps?
✔✔To capture more energy efficiently in the form of ATP.
Why does the body store glucose as glycogen?
✔✔So it can be quickly converted and used in cellular respiration when needed.
