Cellular Respiration Exam questions

Which of the following is the primary purpose of cellular respiration in cells?

• To produce oxygen

• To convert glucose into energy

• To create proteins

• To store fat

During which stage of cellular respiration is the majority of ATP produced?

• Glycolysis

• Krebs Cycle

• Electron Transport Chain

• Fermentation

Explain how the structure of the mitochondrion is related to its function in cellular respiration.

• The smooth outer membrane allows for easy passage of molecules.

• The folded inner membrane increases surface area for ATP production.

• The matrix contains enzymes for glycolysis.

• The intermembrane space stores glucose.

Which of the following best describes the role of oxygen in cellular respiration?

• Oxygen is used to break down glucose in glycolysis.

• Oxygen acts as the final electron acceptor in the electron transport chain.

• Oxygen is converted into carbon dioxide during the Krebs cycle.

• Oxygen is produced as a byproduct of cellular respiration.

Predict what would happen to the process of cellular respiration if the inner mitochondrial membrane were damaged.

• ATP production would increase.

• The Krebs cycle would stop.

• The electron transport chain would be disrupted.

• Glycolysis would not occur.

Which of the following equations represents the overall process of cellular respiration?

Analyze the impact of a lack of glucose on the process of cellular respiration.

• The Krebs cycle would continue unaffected.

• ATP production would decrease significantly.

• Oxygen consumption would increase.

• The electron transport chain would produce more ATP.

Which of the following processes occurs in the cytoplasm of the cell during cellular respiration?

• Krebs Cycle

• Electron Transport Chain

• Glycolysis

• Oxidative Phosphorylation

Evaluate the efficiency of cellular respiration in terms of energy conversion compared to fermentation.

• Cellular respiration is less efficient than fermentation.

• Cellular respiration is more efficient than fermentation.

• Both processes are equally efficient.

• Fermentation produces more ATP than cellular respiration.

What is the role of NADH and FADH2 in cellular respiration?

• They act as enzymes in glycolysis.

• They transport electrons to the electron transport chain.

• They are used to break down glucose.

• They are converted into ATP directly.
