A Level Photosynthesis

What is the pigment in chloroplasts that performs photosynthesis?

• Chlorosynthesis
• Chlorophyll
• ADP
• Electron Transport

The stacks of disks in the chloroplast are called:

• Lamellae
• Grana
• Stroma
• Thylakoid

The interior space of the chloroplast is called:

• Lamellae
• Grana
• Stroma
• Thylakoids

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 does the light independent reaction take place?

• Matrix
• Stroma
• Thylakoid membrane
• Cytoplasm

What reactants are needed for the Calvin cycle?

• Carbon dioxide
• Carbon dioxide, ATP and NADPH

• Carbon dioxide and glucose
• Oxygen and water

Where do the light reactions happen?

• mitochondria membrane
• thylakoid membrane
• stroma
• central vacuole

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

Which of the following equations represents the overall chemical reaction for photosynthesis?

• 6O₂+ 6H₂O → C₆H₁₂O₆+ 6O₂

• C₆H₁₂O₆ + 6H₂O→ 6O₂+ 6O₂

• 6CO₂+ 6H₂O→ C₆H₁₂O₆+ 6O₂

• 6O₂ + 6H₂O→ C₆H₁₂O₆ + 6CO₂

What happens to the O₂ created in the light phase?

• Is transferred to the Calvin Cycle
• Donates its electrons to the Chlorophyll molecules
• Provides a carbon to form the unstable 6-carbon molecule
• Diffuses out through the stoma
