Photosynthesis and Cellular Respiration Quiz

What is the primary location where photosynthesis occurs within plant cells?

• Ribosomes

• Mitochondria

• Nucleus

• Chloroplasts

Which pigment is primarily responsible for absorbing light energy in plants?

• Chlorophyll

• Anthocyanins

• Xanthophylls

• Carotenoids

In which regions of the light spectrum does chlorophyll absorb the most energy?

• Orange and red

• Green and yellow

• Yellow and blue

• Blue-violet and red

What are the two main phases of photosynthesis?

• Light-dependent reactions and Calvin cycle

• Light-independent reactions and glycolysis

• Light-dependent reactions and Krebs cycle

• Calvin cycle and electron transport chain

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

• In the stroma

• In the nucleus

• In the thylakoid membranes

• In the cytoplasm

What is the primary function of photosystem II in the light-dependent reactions?

• To split water molecules

• To produce glucose

• To generate NADPH

• To fix carbon dioxide

What is the main product of the Calvin cycle?

• Oxygen

• NADPH

• ATP

• Glucose

How does the Calvin cycle differ from the Krebs cycle?

• It occurs in the mitochondria

• It produces ATP

• It releases energy

• It fixes carbon dioxide into carbohydrates

Which molecule acts as an electron carrier in photosynthesis?

• NADPH

• FADH2

• NADH

• ATP

What is the relationship between photosynthesis and cellular respiration?

• Photosynthesis releases energy, while respiration stores it

• They both occur in the chloroplast

• They are identical processes

• Photosynthesis stores energy, while respiration releases it
