• 2

• 4

• 18

• 36

What is the role of water in the light-dependent reactions of photosynthesis?

• It is split to release oxygen

• It is used to produce glucose

• Acts as an electron acceptor

• Provides the carbon atoms for glucose synthesis

Which of the following statements correctly compares cellular respiration and photosynthesis?

• Both processes occur in the mitochondria.

• Photosynthesis releases energy, while cellular respiration stores energy.

• Cellular respiration produces oxygen, while photosynthesis uses oxygen.

• Photosynthesis converts solar energy into chemical energy, while cellular respiration converts chemical energy into ATP.

• 2

• 4

• Approximately 30-32

• Approximately 36-38

Which of the following is a similarity between cellular respiration and photosynthesis?

• Both processes occur in animals.

• Both involve the conversion of energy from one form to another.

• Both produce glucose as a final product.

Which of the following is the correct equation for PHOTOSYNTHESIS?

• 6CO₂ + 6H₂O --> 6O₂ + C₆H₁₂O₆
