Photosynthesis Quiz

What is the role of photosystems in photosynthesis?

• They store energy in the form of glucose.

• They generate and emit excited electrons.

• They break down water molecules.

• They transport oxygen out of the cell.

Which molecule is responsible for carbon fixation in photosynthesis?

• ATP

• NADP

• Rubisco

• Chlorophyll

Where do the light-dependent reactions of photosynthesis occur?

• Stroma

• Thylakoids

• Cytoplasm

• Nucleus

What is the function of the stroma in chloroplasts?

• It contains chlorophyll for light absorption.

• It is the site of light-dependent reactions.

• It has enzymes and a suitable pH for the Calvin cycle.

• It connects thylakoid stacks.

What evidence supports the endosymbiotic origin of chloroplasts?

• Presence of chlorophyll

• Double membrane structure

• Ability to perform photosynthesis

• Production of glucose

What is the role of accessory pigments in photosystems?

• They absorb water.

• They release oxygen.

• They transfer energized electrons to a central reaction center.

• They produce glucose.

Where are photosystems located within a plant cell?

• Mitochondria

• Thylakoid membrane

• Nucleus

• Cytoplasm

What is the main purpose of light dependent reactions in photosynthesis?

• To produce glucose

• To convert light energy into chemical energy (ATP)

• To absorb carbon dioxide

• To release nitrogen

What is the by-product of Photosystem II during the light dependent reactions?

• Glucose

• Oxygen

• Carbon dioxide

• Nitrogen

What is the function of ATP synthase in the light dependent reactions?

• It absorbs light.

• It catalyzes ATP synthesis using protons.

• It releases carbon dioxide.

• It stores glucose.
