In which way are photosynthesis and cellular respiration different?

• Cellular respiration stores ATP, while photosynthesis releases ATP.
• Cellular respiration produces oxygen, while photosynthesis uses oxygen.
• Photosynthesis releases energy, while cellular respiration stores energy.
• Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.

What is the correct equation for cellular respiration?

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

In cellular respiration, the electron transport chain takes place in

• the membrane of the mitochondrion
• the folds of the mitochondrion
• the cytoplasm
• the cell nucleus

ATP is called a cell's "energy currency" because

• ATP catalyzes all metabolic reactions
• ATP allow one organelle to be exchanged for another between cells
• glucose is made of ATP
• most of the energy that drives metabolism is supplied by ATP
