Photosynthesis Review

Where do the light-dependent reactions occur? 

• thylakoid membrane
• stroma
• lumen
• mitochondria

Where do the light-independent reactions occur?

• thylakoid
• stroma
• lumen
• mitochondria

18 is referring to a stack of these disc-shaped structures. What is this stack known as? 

• lumen
• thylakoid
• granum
• stroma

 During chemiosmosis

• Carbon is fixed.
• ATP is synthesized from ADP
• NADPH is synthesized from NADP+
•  Electrons are removed from chlorophyll molecules.

Where does Photosystem I get its electrons?

• From photosystem II
• From NADP+
• From the splitting of water
• From carbon dioxide

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

At the end of the photosystem I electron transport chain, electrons

• Combine with NADP+ to form NADPH
• Combine with ADP to form ATP
• Enter photosystem II
• Are ejected from the membrane to the stroma

Which of the following are products of the light reactions that are utilized in the Calvin cycle?

• CO₂ and glucose
• H₂O and O₂
• ADP and ATP
• ATP and NADPH

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

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

In green plants, the primary function of the Calvin cycle is to

• Use ATP to release carbon
• Split water to release oxygen.
• Construct simple sugars from carbon dioxide.
• Use NADPH to release carbon
