What is the process by which bacteria use energy from inorganic compounds to synthesize food?

• chemosynthesis
• fermentation
• cellular respiration
• all of these

Why are photosynthesis and cellular respiration often considered opposites?

• Photosynthesis produces twice as many ATP molecules as cellular respiration does.
• Water is released during photosynthesis and consumed during cellular respiration.
• Photosynthesis occurs during the day, and cellular respiration occurs at night.
• Oxygen is produced during photosynthesis and used during cellular respiration.

Which of the following correctly describes how a diagram of cellular respiration would differ from a diagram of photosynthesis?

• The cellular-respiration diagram would show electromagnetic waves as the final product.
• The cellular-respiration diagram would show glucose as the main source of energy.
• The cellular-respiration diagram would show energy stored in large protein molecules.
• The cellular-respiration diagram would show water as the main source of chemical energy.

• The reactants of photosynthesis are the products of cellular respiration.
• The reactants of photosynthesis are sugar and oxygen to be used in cellular respiration.
• The products of photosynthesis are the same as the products of cellular respiration.
