Light-Dependent Reaction Flashcard

Front

What is the main product of the light-dependent reactions?

Back

Oxygen, NADPH, and ATP are produced, but glucose is not.

Front

Where do the light-dependent reactions occur in a plant cell?

Back

In the thylakoid membrane of the chloroplast.

Front

What is the primary purpose of the light-dependent reactions?

Back

To capture energy from sunlight and convert it into chemical energy in the form of ATP and NADPH.

Front

Which organelle is responsible for photosynthesis in plant cells?

Back

The chloroplast.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy needed to break down water molecules.

Front

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

Back

ATP and NADPH.

Front

What is the relationship between light-dependent reactions and the Calvin cycle?

Back

The light-dependent reactions provide the energy (ATP) and reducing power (NADPH) needed for the Calvin cycle.

Front

What happens to water molecules during the light-dependent reactions?

Back

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

Front

What is photolysis?

Back

The process of using light energy to split water molecules during photosynthesis.

Front

What is the significance of NADPH in photosynthesis?

Back

NADPH is used as a reducing agent in the Calvin cycle to help convert carbon dioxide into glucose.
