Photosynthesis B

What does ATP synthase do?

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

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

What is the purpose of splitting water in PS2 of the light dependent reaction?

• Provides e- for PS2 and H+ for the thylakoid space
• To produce Oxygen for animals
• There is no purpose

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.

What is this molecule..? 

• ADP
• ATP
• AMP
• Carbohydrate
