Light Dependent Reaction

Front

What are the two products of the light reactions that are needed for the Calvin cycle?

Back

NADPH and ATP

Front

What provides the energy required to pump H+ ions into the H ion reservoir?

Back

Electron Transport Chain

Front

What supplies the electron that is lost in PS II?

Back

Water

Front

What is the role of sunlight during photosynthesis?

Back

Break down the water

Front

What happens when light strikes the chlorophyll molecules of photosystems I and II?

Back

Light causes electrons to get excited (gain energy) and travel down the electron transport chain embedded in the thylakoid membrane.

Front

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

Back

To convert solar energy into chemical energy in the form of ATP and NADPH.

Front

Where do the light-dependent reactions take place?

Back

In the thylakoid membranes of chloroplasts.

Front

What is the role of water in the light-dependent reactions?

Back

Water is split to provide electrons, protons, and oxygen.

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.

Front

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

Back

ATP provides the energy needed for various biochemical reactions, including the Calvin cycle.
