Cell Energetics

Where in a plant cell does photosynthesis take place

• Palisade cells

• Chlorophyll

• Chloroplasts

• Vacuole

What is the purpose of photosynthesis?

• To release energy

• To create glucose

• To grow

• To get oxygen for respiration

Which of these is the correct equation for photosynthesis?

• 6O₂ + C₆H₁₂O₆ --> 6CO₂ + 6H₂O

• 6O_{2 +} 6CO_{2 -->} C₆H₁₂O_{6 +} 6H₂O

• 6CO₂ + 6H₂O --> C₆H₁₂O₆ + 6O₂

• 6CO₂ + 6H₂O --> O₂ + C₆H₁₂O₆

What are the products of photosynthesis?

• Oxygen and Energy

• Carbon Dioxide and Glucose

• Glucose and Oxygen

What molecule absorbs sunlight for photosynthesis?

• chloroplast
• thylakoid
• grana
• chlorophyll

What supplies the electrons during photolysis?

• oxygen

• water

• glucose

• rubisco

Choose the statement that best describes light reaction.

Which cell process is represented by this equation:
C₆H₁₂O₆ + 6O₂ →          6CO₂  +  6H₂O +  ATP

• diffusion
• photosynthesis
• cell respiration
• mitosis

What are the three stages that make up cellular respiration?

• light reactions, calvin cycle and electron transport
• glycolysis, kreb's cycle and Calvin cycle
• Glycolysis, Kreb's cycle and electron transport
