Cellular Respiration - Quiz

1. Which statement best describes the purpose of cellular respiration?

• To transport energy throughout the mitochondria
• To release energy from glucose and convert it into ATP
• To release energy from ATP and convert it into glucose
• To convert oxygen into carbon dioxide, releasing energy

2. TRUE or FALSE: All living organisms carry out cellular respiration.

• TRUE
• FALSE

3. Select the correct word equation for aerobic cellular respiration:

• glucose + carbon dioxide --> oxygen + water
• glucose + water --> carbon dioxide + oxygen +ATP
• glucose + oxygen --> carbon dioxide + water+ ATP
• glucose + pyruvate --> oxygen + carbon dioxide + ATP

4. How do animals obtain the glucose needed for cellular respiration?

• Osmosis
• Consumption of other organisms
• Photosynthesis
• Facilitated diffusion
• Fermentation

5. How do plants obtain the glucose needed for cellular respiration?

• Chemiosmosis
• Osmosis
• Active transport
• Photosynthesis
• Fermentation

8. Which stages of aerobic cellular respiration require oxygen? Select all that apply.

• The Krebs Cycle
• Glycolysis
• The Electron Transport Chain
• Fermentation

9. What is the correct order of the stages of aerobic cellular respiration, from first to last?

• Krebs Cycle --> Glycolysis --> Electron Transport Chain
• Glycolysis --> Electron Transport Chain --> Krebs Cycle
• Electron Transport Chain --> Krebs Cycle --> Glycolysis
• Glycolysis --> Krebs Cycle --> Electron Transport Chain

11. What is the function of NADH and FADH2?

• To transport electrons to the electron transport chain
• To bind with pyruvate to form Acetyl-CoA
• To bind with hydrogen ions and form water
• To release energy for the cell

13. The flow of electrons through the Electron Transport Chain causes Hydrogen ions (H+) to get pumped into the mitochondrial intermembrane space. Hydrogen ions (H+) have the same charge as:

• Protons
• Neutrons
• Electrons

14. Which enzyme in the electron transport chain has the function of generating ATP molecules? Hit it is what moves the H+ ions Give your answer as two words with no period at the end.
