Cellular Respiration Quiz

What is the overall chemical equation for cellular respiration?

• CO2 + H2O → C6H12O6 + 6O2 + ATP

• C6H12O6 + 6O2 → 6CO2 + 6H2O + Glucose

• C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

• 6CO2 + 6H2O + ATP → C6H12O6 + 6O2

Name the three stages of cellular respiration.

• Glycolysis, Krebs cycle, Electron transport chain

• Photosynthesis, Fermentation, Oxidative phosphorylation

• Anaerobic respiration, Aerobic respiration, Oxidative phosphorylation

• ATP synthesis, Lactic acid production, Citric acid cycle

Where does glycolysis take place in the cell?

• cytoplasm

• nucleus

• mitochondria

• endoplasmic reticulum

What is the net ATP gain in glycolysis?

• 10 ATP

• 5 ATP

• 0 ATP

• 2 ATP

What is the purpose of the Krebs cycle?

• To store genetic information

• To produce energy for the cell in the form of ATP and generate precursor molecules

• To produce oxygen for the cell

• To regulate body temperature

What is the role of oxygen in cellular respiration?

• Oxygen is used to release carbon dioxide from the cells

• Oxygen helps in the breakdown of glucose into water and carbon dioxide

• Oxygen is responsible for converting ADP to ATP in the mitochondria

• Oxygen is used as the final electron acceptor in the electron transport chain to produce ATP.

What are the end products of the electron transport chain?

• NADH and FADH2

• Lactic acid and pyruvate

• Glucose and carbon dioxide

• ATP and water

What is the difference between aerobic and anaerobic respiration?

• Aerobic respiration requires carbon dioxide, while anaerobic respiration requires oxygen.

• Aerobic respiration occurs in plants, while anaerobic respiration occurs in animals.

• Aerobic respiration requires oxygen, while anaerobic respiration does not require oxygen.

• Aerobic respiration produces more energy than anaerobic respiration.

How is cellular respiration related to photosynthesis?

• They have no relationship to each other

• They both produce the same end products

• They are opposite processes, with the products of one being the reactants of the other.

• Cellular respiration is a type of photosynthesis
