Multiple Choice

What is the main purpose of the Krebs Cycle in cellular respiration?

• To break down glucose into pyruvic acid

• To produce large amounts of ATP and electron carriers

• To convert pyruvic acid into glucose

• To generate oxygen for the cell

Multiple Choice

What is the main function of the electron transport chain in cellular respiration?

• To break down glucose

• To produce water

• To generate a large amount of ATP

• To release carbon dioxide

Multiple Choice

Why is cellular respiration important for living organisms?

• It helps organisms move faster

• It allows organisms to convert food into usable energy

• It helps organisms grow taller

• It allows organisms to reproduce

Multiple Choice

Which of the following is the correct chemical equation for cellular respiration?

• C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

• 6CO2 + 6H2O → C6H12O6 + 6O2 + ATP

• C6H12O6 + 6CO2 → 6O2 + 6H2O + ATP

• 6O2 + ATP → C6H12O6 + 6CO2 + 6H2O
