C1.3 Photosynthesis HL

What is the process by which light energy is converted into chemical energy during photosynthesis?

• Glycolysis

• Photosynthesis

• Krebs cycle

• Fermentation

Which of the following is a product of photosynthesis?

• Carbon dioxide

• Oxygen

• Water

• Glucose

What is the purpose of separating photosynthetic pigments using chromatography?

• To release oxygen

• To expand the range of absorbed light wavelengths

• To increase the plant's water intake

• To absorb more sunlight

What is the main factor that affects the rate of photosynthesis in plants?

• Temperature

• Humidity

• Wind speed

• Soil pH

In carbon dioxide enrichment experiments, what is the purpose of pumping carbon dioxide into the area?

• To reduce the light intensity

• To study the impact on plant growth and photosynthesis

• To increase the oxygen levels

• To decrease the temperature

Where do the light-dependent reactions of photosynthesis take place?

• Stroma

• Thylakoid intermembrane space

• Cytoplasm

• Nucleus

What is the main function of Rubisco in the Calvin cycle?

• Synthesis of Triose Phosphate

• Carbon Fixation

• Reduction of NADP

• Regeneration of RuBP

What is the primary role of ATP in the light-independent reactions of photosynthesis?

• To reduce NADP

• To regenerate RuBP

• To convert carbon dioxide into carbohydrates

• To provide energy for anabolic reactions

What is the purpose of cyclic photophosphorylation in photosynthesis?

• To produce reduced NADP

• To generate ATP using only photosystem I

• To reduce carbon dioxide to triose phosphate

• To synthesize glucose in the Calvin cycle

Why are the light-dependent and light-independent reactions of photosynthesis considered interdependent?

• Because the products of one are needed for the other to function

• Because they use the same enzymes

• Because they both involve the synthesis of ATP

• Because they both occur in the stroma
