Photosynthesis Quiz

Which of the following best describes the location of light-dependent reactions?

• Stroma

• Thylakoid membrane

• Cytoplasm

• Mitochondria

The main products of the light-dependent reactions are:

• CO₂ and glucose

• O₂, ATP, and NADPH

• ATP and pyruvate

• Glucose and starch

Which molecule is a waste product of the light-dependent reactions?

• Glucose

• Oxygen

• ATP

• NADPH

The Calvin Cycle is also known as:

• Krebs Cycle

• Light reaction

• Dark reaction / Light-independent reaction

• Glycolysis

What is the final product of the Calvin Cycle?

• Oxygen

• Glucose

• ATP

• NADPH

Which of the following links the two stages of photosynthesis?

• ATP and NADPH

• Oxygen and glucose

• Water and carbon dioxide

• Sunlight and chlorophyll

During the light-dependent reactions, which process generates ATP?

• Photolysis

• Carbon fixation

• Chemiosmosis

• Glycolysis

Which stage requires carbon dioxide (CO₂) as a reactant?

• Light-dependent reaction

• Light-independent reaction (Calvin Cycle)

• Both stages

• Neither stage

In photosynthesis, the role of chlorophyll is to:

• Absorb carbon dioxide

• Split glucose

• Capture light energy

• Produce oxygen

Which best describes the relationship between the two stages of photosynthesis?

• Independent processes

• Calvin Cycle provides ATP for the light reactions

• Light-dependent reactions supply ATP and NADPH for the Calvin Cycle

• Both stages occur only in darkness
