Cellular Respiration/Glycolysis

How do organisms get the energy they need?

• By burning food molecules and releasing energy as heat

• By breathing oxygen into the lungs and combining it with CO2

• By breaking down food molecules gradually and capturing their chemical energy

• By using the sun's energy to break down food molecules and form chemicals

Which of the following is NOT a stage of cellular respiration?

• fermentation

• electron transport

• glycolysis

• Krebs cycle

Which of the following is the correct sequence of events in cellular respiration?

• glycolysis --> fermentation --> Krebs cycle

• Krebs cycle --> electron transport --> glycolysis

• glycolysis --> Krebs cycle --> electron transport

• Krebs cycle --> glycolysis --> electron transport

What is the correct equation for cellular respiration?

• 6 O2 + C6H12O6 --> 6 CO2 + 6 H20 + ATP

• 6 O2 + C6H1206 + ATP --> 6 CO2 + 6 H20

• 6 CO2 + 6 H2O --> 6 O2 + C6H12O6 + ATP

• 6 CO2 + 6 H20 + ATP --> 6 O2 + C6H12O6
