Unit 4: Energy Review

What is the relationship between photosynthesis and cellular respiration?

• They are unrelated biological processes.

• Photosynthesis consumes carbon dioxide, while cellular respiration produces it.

• Cellular respiration occurs in animals, while photosynthesis occurs in plants.

• Photosynthesis produces oxygen, which is not used in cellular respiration.

What are the reactants required for photosynthesis?

• Glucose and oxygen

• Carbon dioxide, water, and sunlight

• Nitrogen, phosphorus, and potassium

• Oxygen, carbon, and hydrogen

What is the chemical formula for glucose produced during photosynthesis?

• CO2 + H2O

• C6H12O6

• O2

• H2O

Which of the following is the correct balanced chemical equation for photosynthesis?

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

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

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

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

What are the products of photosynthesis?

• Carbon dioxide and water

• Nitrogen and phosphorus

• Glucose and oxygen

• Sunlight and heat

What are the inputs for the Light-Dependent Reactions in photosynthesis?

• Carbon dioxide and Glucose

• Oxygen and ATP

• Sunlight and Water

• ATP and NADPH

What is released as a byproduct during the Light-Dependent Reactions?

• Carbon dioxide

• Glucose

• Oxygen

• Water

Which of the following is NOT an output of the Light-Independent Reactions (Calvin Cycle)?

• Glucose

• ADP

• Oxygen

• Water

What is the purpose of Carbon Fixation in the Calvin Cycle?

Where do the Light Reactions of photosynthesis take place within the chloroplast?

• Stroma

• Thylakoid

• Mitochondria

• Calvin Cycle
