Light Dependent Reactions

Front

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

Back

ATP synthase facilitates the diffusion of hydrogen ions (H+) to produce ATP.

Front

What are NADPH and ATP classified as in the context of photosynthesis?

Back

NADPH and ATP are short-term energy carriers used in the light-dependent reactions.

Front

What is the purpose of splitting water in Photosystem II (PS2) during the light-dependent reactions?

Back

The splitting of water provides electrons (e-) for PS2 and hydrogen ions (H+) for the thylakoid space.

Front

During which stage of photosynthesis do plants utilize carbon dioxide to produce glucose?

Back

Plants use carbon dioxide during the light-independent stage, also known as the Calvin Cycle.

Front

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

Back

Glucose is NOT a product of the light reactions.

Front

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

Back

The two main products are ATP and NADPH.

Front

What role does light play in the light-dependent reactions?

Back

Light energy is absorbed by chlorophyll and used to energize electrons.

Front

What is the significance of the thylakoid membrane in the light-dependent reactions?

Back

The thylakoid membrane houses the proteins and pigments necessary for the light-dependent reactions.

Front

How does the electron transport chain function in the light-dependent reactions?

Back

The electron transport chain transfers energized electrons, leading to the production of ATP and NADPH.

Front

What is photolysis in the context of photosynthesis?

Back

Photolysis is the process of splitting water molecules using light energy to release oxygen.
