Photosynthesis Light and Dark Reactions

Where do the light reactions of photosynthesis take place?

• Stroma

• Cytoplasm

• Thylakoid disks

• Nucleus

What are the main energy-carrying molecules produced during the light reactions of photosynthesis?

• Glucose and Oxygen

• ATP and NADPH

• Carbon Dioxide and Water

• ADP and NADP+

What is the primary purpose of the Calvin cycle (dark reaction) in photosynthesis?

• To split water molecules and release oxygen

• To capture light energy

• To convert carbon dioxide into glucose

• To recharge ADP and NADP+

How do CAM plants adapt to conserve water in hot environments?

• They create 4-carbon compounds

• They open their stomata at night and close them during the day

• They perform photosynthesis only at night

• They have larger leaves to capture more sunlight
