Cellular Respiration & Photosynthesis

What is the byproduct of cellular respiration?

• Oxygen and glucose.

• Carbon dioxide and water.

• Nitrogen and ammonia.

• Hydrogen and sulfur.

What is the difference between aerobic and anaerobic respiration?

• Aerobic respiration occurs in the absence of oxygen, while anaerobic respiration requires oxygen.

• Aerobic respiration produces more energy than anaerobic respiration.

• Anaerobic respiration occurs in the presence of oxygen, while aerobic respiration does not.

• Aerobic respiration requires oxygen, while anaerobic respiration does not.

Do both photosynthesis and respiration require sunlight?

• True

• False

• Only photosynthesis requires sunlight

• Only respiration requires sunlight

What role do chloroplasts play in photosynthesis?

• They contain chlorophyll and are the site of photosynthesis.

• They absorb water and nutrients from the soil.

• They release oxygen into the atmosphere during respiration.

• They store energy in the form of glucose.

What is fermentation?

• A process that requires oxygen to produce energy.

• A type of anaerobic respiration that occurs in some organisms, producing energy without oxygen.

• A method of photosynthesis in plants.

• A chemical reaction that occurs only in yeast.

What is photosynthesis?

• The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

• A method used by animals to convert food into energy.

• The way in which plants absorb water from the soil.

• A technique for growing plants in artificial environments.

What is the chemical equation for photosynthesis?

• 6CO2 + 6H2O + light energy → C6H12O6 + 6O2

• 6O2 + C6H12O6 → 6CO2 + 6H2O + light energy

• C6H12O6 + 6O2 → 6CO2 + 6H2O

• 6H2O + 6CO2 → C6H12O6 + 6O2 + light energy

How is cellular respiration different from photosynthesis?

• Photosynthesis produces glucose, cellular respiration produces energy.

• Photosynthesis occurs in the mitochondria, cellular respiration occurs in the chloroplasts.

• Photosynthesis produces oxygen, cellular respiration produces carbon dioxide.

• Photosynthesis uses carbon dioxide, cellular respiration uses oxygen.

Where does cellular respiration take place?

• In the mitochondria.

• In the nucleus.

• In the ribosomes.

• In the cytoplasm.

What is the purpose of cellular respiration?

• To break down food to create energy.

• To store energy for later use.

• To produce oxygen for photosynthesis.

• To eliminate waste products from the cell.
