Unit 3: Photosynthesis and Cellular Respiration - Concepts 4 & 5

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

Which of the following is the correct equation for PHOTOSYNTHESIS?

• 6CO₂ + 6H₂O → 6O₂ + C₆H₁₂O₆

• 6CO₂ + C₆H₁₂O₆ + 6H₂O → O₂

• 6O₂ +6H₂O → 6CO₂ +C₆H₁₂O₆

• C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂

What is the purpose of photosynthesis?

• make glucose
• make ATP
• make light
• release carbon dioxide

The first step in getting energy in the cell by breaking down glucose is known as

• the Krebs cycle
• electron transport
• fermentation
• glycolysis

The two main stages of photosynthesis are the

• light reactions and respiration
• dark reactions and the Calvin cycle 
• light reactions and the Calvin cycle
• dark reactions and fermentation
