• To convert chemical energy into ATP

• To create glucose

Which process occurs in the absence of oxygen?

• Diffusion

• Oxygen delivery

• Anaerobic respiration

• Aerobic respiration

What is the main energy currency of the cell?

• Glucose

• Oxygen

• Carbon dioxide

• ATP

What is produced as a byproduct of metabolic processes in cells?

• Oxygen

• Carbon dioxide

• Glucose

• ATP

What is the role of diffusion in tissue respiration?

• It requires energy from the cell

• It is an active process

• It involves the use of ATP

• It is a passive process

What drives the movement of oxygen and carbon dioxide across cell membranes?

• Temperature gradients

• Partial pressure gradients

• Concentration of glucose

• Presence of ATP

What is the balanced chemical equation for aerobic cellular respiration?

• C₆H₁₂O₆ + 6CO₂ → 6O₂ + 6H₂O + ATP

• 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

• 6O₂ + 6H₂O → C₆H₁₂O₆ + 6CO₂

• C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP

What happens to carbon dioxide produced in cells?
