Photosynthesis

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

Use the diagram to answer the question. Between which parts of the molecule must the bonds be broken to form an ADP molecule?

• A and B
• A and C
• B and C
• C and D

The interior space of the chloroplast is called:

• Lamellae
• Grana
• Stroma
• Thylakoids

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

How would the concentration of CO₂ in water affect photosynthesis?

• The higher the CO₂, the greater the rate
• The higher the CO₂, the lower the rate
• CO₂ concentration doesn't affect photosynthesis
• a greater rate of photosynthesis causes higher CO₂ concentrations 

What is the first stop in photosynthesis process?

• Photosystem I
• Photosystem II
• Electron Transport Chain
• stroma

What gas goes into the plant before photosynthesis?

• Carbon Dioxide
• Carbon Monoxide
• Oxygen
• Nitrogen

The stacks of disks in the chloroplast are called:

• Lamellae
• Grana
• Stroma
• Thylakoid

How would light intensity generally affect the rate of photosynthesis?

• Increases the rate, up to a point
• Increases the rate
• Decreases the rate
• No relationship to the rate

What is the output of photosynthesis?

• ATP
• Glucose
• CO₂
• light
