Photosynthesis Review

Chlorophyll absorbs a higher percentage of _____ and _______ light.

• purple and green
• red and blue
• black and orange
• yellow and green

Most plants appear green because chlorophyll

• absorbs green light.
• absorbs violet light.
• reflects green light.
• does not absorb violet light.

The reactants of photosynthesis are

• sugar and water.
• sugar and oxygen.
• carbon dioxide and water.
• carbon dioxide and oxygen.

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 function of NADPH and ATP?

• They absorb light
• They power the light-dependent reactions
• They are light-reflecting pigments
• They are short term energy carriers

Where do the light-dependent reactions occur? 

• thylakoid membrane
• stroma
• mesophyll
• mitochondria

Which of the following is NOT a product of the light-dependent reactions?

• ATP
• NADPH
• Oxygen
• Glucose

What is the primary function of the light-dependent reactions of photosynthesis?

• To produce glucose
• To produce NADPH and ATP
• To use ATP
• To produce RuBP

Plants need carbon dioxide from their environment to produce glucose during which stage of photosynthesis? 

• The light-dependent stage
• The light-independent stage (The Calvin Cycle)
• The electron transport chain
• ATP formation

How many sugar molecules are produced from every six molecules of carbon dioxide that enter the Calvin cycle?

• 1
• 3
• 6
• 12
