Back

Produce ATP from ADP.

Front

What are the roles of the electron transport chain at the end of Photosystem I in the light reactions?

Back

Transfer electrons.

Front

Where do the light reactions occur in the chloroplast?

Back

Thylakoid Disks.

Front

What are the two primary steps of photosynthesis?

Back

Light reactions and Calvin cycle reactions.

Front

What are the roles of the electron transport chain between Photosystem II and Photosystem I in the light reactions?

Back

Transfer electrons.

Front

What is photosynthesis?

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths.

Front

What is the Calvin cycle?

Back

The set of chemical reactions that take place in chloroplasts during photosynthesis, where carbon dioxide is converted into glucose.

Front

What is the significance of the hydrogen ion (proton) gradient in the light reactions?

Back

It drives ATP synthesis through ATP synthase.

Front

What are the products of the light reactions?

Back

ATP and NADPH.
