Light Dependent Reactions of Photosynthesis

Front

What is the main function of ATP synthase in photosynthesis?

Back

ATP synthase creates ATP during chemiosmosis.

Front

During which process is water split in the light dependent reactions?

Back

Water is split during photosystem 2 of the light dependent reaction.

Front

How is ATP formed in the light dependent reactions?

Back

ATP is formed by the process of chemiosmosis.

Front

What provides the electrons lost in photosystem I (PSI)?

Back

The electrons lost in PSI are supplied by the electrons from photosystem II (PS II).

Front

What happens to the oxygen produced in the light phase of photosynthesis?

Back

The oxygen diffuses out through the stoma.

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 chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs light energy, which is used to energize electrons.

Front

What is the significance of the electron transport chain in photosynthesis?

Back

The electron transport chain helps in the production of ATP and NADPH.

Front

What is photolysis in the context of photosynthesis?

Back

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

Front

What is the role of NADP+ in the light dependent reactions?

Back

NADP+ acts as an electron carrier, becoming NADPH.
