Light Dependent Reaction

Front

Where do the light reactions of photosynthesis occur?

Back

The light reactions occur in the thylakoid membrane of the chloroplasts.

Front

What is the basic unit of light?

Back

The basic unit of light is called a photon.

Front

Which of the following is NOT a product of the light reactions: ATP, NADPH, or Glucose?

Back

Glucose is NOT a product of the light reactions.

Front

What is the primary function of the light reactions in photosynthesis?

Back

The primary function of the light reactions is to convert light energy into chemical energy in the form of ATP and NADPH.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight is used during photosynthesis to break down water molecules.

Front

What are the two main products of the light-dependent reactions?

Back

The two main products of the light-dependent reactions are ATP and NADPH.

Front

What is the significance of the thylakoid membrane in photosynthesis?

Back

The thylakoid membrane is where the light-dependent reactions take place, housing the necessary proteins and pigments for capturing light energy.

Front

What happens to water molecules during the light reactions?

Back

Water molecules are split (photolysis) to release oxygen, protons, and electrons.

Front

How do ATP and NADPH produced in the light reactions contribute to the Calvin cycle?

Back

ATP provides energy, and NADPH provides reducing power for the conversion of carbon dioxide into glucose in the Calvin cycle.

Front

What is the role of chlorophyll in the light reactions?

Back

Chlorophyll absorbs light energy, which is essential for driving the light-dependent reactions.
