Which of the following statements about photosynthesis is incorrect? Photosynthesis

• results in the transformation of radiant energy into chemical energy

• requires the use of enzymes to speed up the process

• is dependent on the presence of oxygen since it is an anabolic reaction

• utilises red and blue wavelengths of light

The second stage of photosynthesis where carbon dioxide is used to form glucose in the stroma of a chloroplast. What is the stage known as?

• Light Dependent Stage

• Light Independent Stage

• Neither stage as CO2 is an output

• Both stages equally

Which of the following is the correct sequence of events for the light dependent stage of photosynthesis?

• Light energy absorbed by chlorophyll → electrons are excited → ATP is produced → electrons are moved between photosystems → NADPH is produced.

• Light energy absorbed by chlorophyll → water molecules are split → electrons are moved between photosystems → NADPH is oxidised to NADP+.

• Water molecules are split → light energy absorbed chlorophyll → NADPH is produced.

• Electrons are excited by light energy → electrons are moved between photosystems → NADP+ is reduced to NADPH.

In photosynthesis, the light dependent stage produces high-energy coenzyme molecules. Identify on the diagram below the location in the chloroplast where this stage occurs.

• In the thylakoid membranes (grana)

• In the stroma

• In the cell wall

• In the cytoplasm

Which one of the following molecules is required for the Calvin cycle to proceed?

• Rubisco enzyme

• NADH

• Water

• Chlorophyll

What is the main role of ATP produced during the light-dependent stage of photosynthesis?

• Supplies energy to drive the reactions in the Calvin cycle

• Acts as a pigment to absorb sunlight

• Breaks down glucose

• Transports water into the cell
