Cell Respiration Quiz

What is the role of NAD in cell respiration?

• Carrier of oxygen

• Carrier of hydrogen and oxidation by removal of hydrogen

• Carrier of carbon dioxide

• Carrier of glucose

Which process involves the conversion of glucose to pyruvate with a net yield of ATP and reduced NAD?

• Krebs cycle

• Electron transport chain

• Glycolysis

• Photosynthesis

What is the main difference between anaerobic and aerobic respiration?

• Anaerobic respiration requires oxygen, aerobic does not

• Anaerobic respiration occurs in the mitochondria, aerobic does not

• Anaerobic respiration results in a small ATP yield, aerobic results in a large ATP yield
