What role does cellular respiration play in the water cycle?

It removes H2O from the atmosphere during glycolysis.

It removes H2O from the atmosphere during acetyl CoA formation.

It releases H2O to the atmosphere during the citric acid cycle.

It releases H2O to the atmosphere during electron transport.

What is the main difference between aerobic respiration and anaerobic respiration?

Aerobic respiration requires oxygen to proceed, but anaerobic respiration does not.

Aerobic respiration occurs during photosynthesis, but anaerobic respiration occurs during cellular respiration.

Aerobic respiration produces ATP, but anaerobic respiration does not.

Aerobic respiration involves glycolysis, but anaerobic respiration does not.

Which statement about cellular respiration is true?

It produces oxygen.

It requires water.

It is used by every living cell.

It converts energy to food.

The equation shows cellular respiration. During cellular respiration, glucose combines with oxygen to form carbon dioxide, water, and ATP. What happens to the energy in the bonds in glucose?

The energy is transferred to oxygen.

The energy is transferred to carbon dioxide.

The energy is transferred to water.

The energy is transferred to ATP.

Which statement about anaerobic respiration is true?

Anaerobic respiration prevents muscle fatigue.

Anaerobic respiration generates a high yield of ATP.

Anaerobic respiration is used commercially in the production of beer, wine, bread, yogurt, and cheese.

Anaerobic respiration can provide energy to animals for several days in the absence of oxygen.

What do alcohol fermentation, acetyl CoA formation, and the Krebs cycle have in common?

All produce water.

All produce carbon dioxide.

All produce ATP.

All produce alcohol.

What do aerobic respiration and anaerobic respiration have in common?

Both begin with glycolysis.

Both occur in mitochondria.

Both require oxygen to proceed.

Both end with the electron transport chain.

During glycolysis, glucose is broken down into two molecules of pyruvate. What is the main transformation that occurs during glycolysis?

Glycolysis produces ATP and pyruvate by oxidizing water.

Glycolysis produces ATP and pyruvate by oxidizing glucose and NAD+.

Glycolysis produces pyruvate, ATP, and NADH by oxidizing glucose.

Glycolysis produces CO2, ATP, and pyruvate by reducing glucose.
