C1.1.1-5 Cell Respiration

What is the primary goal of cell respiration?

• To generate ATP

• To produce glucose

• To create oxygen

• To form carbon dioxide

Which bond in ATP releases energy when broken?

• Between the first and second phosphate

• Between the second and third phosphate

• Between the carbon and nitrogen atoms

• Between the adenosine and first phosphate

Why is ATP considered a good energy currency for cells?

• It is insoluble in water

• It can cross membranes easily

• It is stable and soluble in water

• It is unstable and reactive

What is the main difference between aerobic and anaerobic respiration?

• Neither uses oxygen

• Both use oxygen

• Anaerobic uses oxygen, aerobic does not

• Aerobic uses oxygen, anaerobic does not

What byproduct is produced during anaerobic respiration in humans?

• Water

• Lactate

• Carbon dioxide

• Ethanol

How many ATP molecules are produced per glucose molecule in aerobic respiration?

• 2 ATP

• 10 ATP

• 30 ATP

• 50 ATP

What is oxygen debt?

• The oxygen consumed during aerobic respiration

• The oxygen produced during photosynthesis

• The amount of oxygen required to break down lactate after anaerobic respiration

• The amount of oxygen needed to start aerobic respiration

Which of the following is NOT a reliable factor to measure in cell respiration experiments?

• Carbon dioxide concentration

• Oxygen concentration

• Glucose concentration

• Heat

What does a respirometer measure?

• Carbon dioxide production

• Oxygen consumption

• Heat generation

• ATP synthesis

Why is it important to control variables in cell respiration experiments?

• To accurately determine the effect of the independent variable

• To make the experiment more complex

• To ensure the experiment is quick

• To increase the number of variables
