Quick recap - respiration vs photosynthesis

What process occurs when light energy is captured by chlorophyll in autotrophs and converted into sugar?

• Photosynthesis

• Cellular Respiration

What are the products of photosynthesis?

• water and carbon dioxide
• oxygen and glucose
• oxygen and carbon dioxide
• oxygen and water

Aerobic cellular respiration takes place when there is

• no oxygen

• available oxygen

• too much water

• too much carbon dioxide

Aerobic cellular respiration takes place in the

• chloroplasts

• mitochondria

• nucleus

• ribosomes

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

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

Why do muscle cells have more mitochondria than skin cells?

• to increase oxygen production in muscles

• muscle cells use more energy than skin cells

• to ensure more carbon dioxide is released

• muscle cells use less energy than skin cells

What is the name of the carbohydrate that is produced in photosynthesis?

• Sucrose

• Dextrose

• Glucose

• Lactose

These are the reactants for photosynthesis.

• H₂O and O₂

• C₆H₁₂O6 and O₂

• H₂O and C₆H₁₂O6

• H₂O and CO₂

What is the primary purpose of cellular respiration?

• to release oxygen from air molecules

• To release energy from ATP molecules

• To break down glucose and transfer its energy to ATP molecules

• To transfer the sun energy into glucose
