Cellular Respiration Concepts

What is the primary purpose of cellular respiration?

• To convert glucose into ATP

• To convert ATP into glucose

• To produce oxygen

• To store energy as fat

What is the correct equation for cellular respiration?

• 6CO₂ + 6H₂O + Energy -> 6O₂ + C₆H₁₂O₆

• 
  6O₂ + C₆H₁₂O₆ + Energy -> 6CO₂ + 6H₂O

• 6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy

• 6CO₂ + 6H₂O -> 6O₂ + C₆H₁₂O₆ + Energy

• FADH2

Which of the following is a waste product of the citric acid cycle?

• Carbon dioxide

• Water

• Glucose

• ATP

Which statement is true regarding cellular respiration?

• Cellular respiration only occurs in autotrophs, photosynthesis occurs only in heterotrophs.

• 
  The reactants of cellular respiration are obtained from the products of photosynthesis.

• The products of cellular respiration are the same as the products of photosynthesis

• 
  The reactants of cellular respiration are identical to the reactants of photosynthesis.
