What does ATP synthase do?

• Create ATP in chemiosmosis.
• Break down ATP in chemiosmosis.
• Break down NADPH. 
• Create NADPH.

Where is chlorophyll found in the chloroplast?

• in the stroma
• within photosystems
• in the ATP synthase
• in the electron carrier molecule

Chlorophyll absorbs _____ and _______ light from the light.

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

What is the function of NADP+?

• It absorbs light
• It is an electron carrier
• It is a light-reflecting pigment
• It acts as long-term energy storage

Chlorophyll absorbs _____ and _______ light from the light.

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

What are the two products of the light reactions that are needed for the calvin cycle?

• NAD and NADPH
• NADP + and Glucose
• NADPH and ATP
• Oxygen and NADPH

What does light do when it strikes the chlorophyll molecules of photosystems I and II?

• Light causes glucose to be synthesized directly inside the chlorophyll molecules of the photosystems.

• Light causes electrons to get excited (gain energy) and travel down the electron transport chain embedded in the thylakoid membrane.

• Light causes the conversion of water into carbon dioxide, oxygen, and electrons.

• Light directly causes carbon dioxide to attach to RuBP during the carbon fixation stage of the Calvin Cycle.

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light + H₂O --> O₂ + Sugar
• CO₂ + sugar + H₂O --> O₂ + light
• _O2 + light + H₂O --> CO₂ + Sugar
• CO₂ + O₂ + H₂O --> Light+ Sugar

What is the source of energy for photosynthesis?

• carbohydrates-chemical
• sunlight-radiant
• heat-thermal
• television-electrical

What are the products of photosynthesis?

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