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?

• Krebs cycle

• Glycolysis

• Electron transport chain

• 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 in the cytosol

• Anaerobic respiration partially digests glucose, aerobic completely breaks it down

• Anaerobic respiration produces a large yield of ATP, aerobic produces a small yield

What is the role of oxygen in aerobic cell respiration?

• Initial electron donor

• Terminal electron acceptor

• Intermediate electron carrier

• Proton donor

What is the function of the mitochondrion in cell respiration?

• Production of glucose

• Production of ATP

• Storage of oxygen

• Conversion of pyruvate to lactate

What is the net gain of ATP molecules during anaerobic respiration?

• 1 ATP

• 2 ATP

• 4 ATP

• 6 ATP

In glycolysis, glucose is split into two molecules of what compound?

• Lactate

• Ethanol

• Pyruvate

• Acetyl CoA

What is the role of NADH in glycolysis?

• It acts as a substrate for ATP production.

• It carries hydrogen to form NAD+.

• It is a hydrogen carrier.

• It converts glucose into pyruvate.

During fermentation in animals, pyruvate is converted into which compound?

• Ethanol

• Carbon dioxide

• Lactic acid

• Acetyl CoA

What is the primary function of mitochondria in eukaryotic cells?

• Photosynthesis

• Protein synthesis

• Aerobic respiration

• DNA replication
