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?

• Krebs cycle

• Glycolysis

• Electron transport chain
