What is the process in which light energy is converted to chemical energy in the form of sugars?

• Cellular respiration

• Photosynthesis

• Glycolysis

• Fermentation

What is the primary site of photosynthesis in most plants?

• Leaves

• Stems

• Flowers

• Roots

What is the name of the fluid-filled space inside the chloroplast?

• Mesophyll

• Thylakoid space

• Granum

• Stroma

What is the net effect of the light-dependent reactions in photosynthesis?

• Produce ATP and NADPH

• Convert water into oxygen

• Release carbon dioxide

• Convert carbon dioxide into sugars

What is the overall reaction of photosynthesis?

• Conversion of oxygen to carbon dioxide

• Conversion of water and carbon dioxide to glucose and oxygen

• Conversion of ATP to ADP

• Conversion of glucose to oxygen

• Conversion of glucose and oxygen to water and carbon dioxide

Why is photosynthesis important?

• It converts light energy into chemical energy for plants and other organisms

• It is the process of breaking down glucose to release energy

• It produces oxygen for cellular respiration

• It releases carbon dioxide into the atmosphere

What is the second step in photosynthesis?

• light-dependent reaction

• calvin cycle

• pyruvate oxidation

• citric acid cycle

• glycolysis

Photosynthesis is a...

• endothermic reaction

• exothermic reaction

• combustion reaction

• neutralization reaction

Photosynthesisers can...

• convert their own energy from the sun's light

• convert glucose from the sun to usable energy

• produce glucose from oxygen and sunlight

• produce chlorophyll for energy

How is ATP used in photosynthesis?

• It is used to breakdown light energy

• It is used to fix carbon from CO₂ to glucose in the CC

• it is used to convert water to oxygen in the LDR

• It is used to feed the chloroplast
