Cellular Respiration

What is the difference between aerobic and anaerobic respiration?

• Aerobic respiration occurs in the absence of oxygen, while anaerobic respiration requires oxygen.

• Aerobic respiration produces more energy than anaerobic respiration, which produces less energy.

• Aerobic respiration occurs in plants only, while anaerobic respiration occurs in animals only.

• Aerobic respiration requires oxygen, while anaerobic respiration does not.

What is the main energy currency of the cell?

• ATP (adenosine triphosphate)

• ADP (adenosine diphosphate)

• GTP (guanosine triphosphate)

• AMP (adenosine monophosphate)

What is the significance of the electron transport chain in cellular respiration?

• It produces the majority of ATP during cellular respiration.

• It is responsible for glycolysis.

• It converts glucose into pyruvate.

• It generates carbon dioxide as a waste product.

What is the chemical formula for glucose?

• C6H12O6

• C5H10O5

• C6H10O6

• C7H14O7

What is the role of oxygen in cellular respiration?

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

• Oxygen is used to produce glucose during photosynthesis.

• Oxygen is a byproduct of cellular respiration.

• Oxygen helps in the breakdown of fatty acids.

What gas is produced by animals during cellular respiration?

• Oxygen

• Nitrogen

• Carbon dioxide

• Hydrogen

What is the Krebs cycle also known as?

• The glycolytic pathway.

• The citric acid cycle.

• The electron transport chain.

• The pentose phosphate pathway.

What is the main purpose of cellular respiration?

• To transform sugar into a usable form of energy (ATP).

• To produce oxygen for photosynthesis.

• To break down proteins for energy.

• To store energy in the form of glucose.

What is the primary product of cellular respiration?

• Glucose

• Oxygen

• ATP

• Carbon Dioxide

What is the net gain of ATP from glycolysis?

• 1 ATP molecule

• 2 ATP molecules

• 3 ATP molecules

• 4 ATP molecules
