Light Dependent Reactions in Photosynthesis

Front

Light dependent reactions occur in which part of the chloroplast?

Back

Thylakoid membranes.

Front

What are the two main processes involved in light dependent reactions?

Back

Non-cyclic and cyclic photophosphorylation.

Front

What is produced during the light dependent reactions?

Back

ATP and NADPH.

Front

What byproduct is released during the light dependent reactions?

Back

Oxygen.

Front

What is the role of ATP and NADPH in photosynthesis?

Back

They are essential for the light independent reactions that convert carbon dioxide into glucose.

Front

What happens to light energy in photosystem II?

Back

It is absorbed, exciting a pair of electrons.

Front

What process produces ATP through chemiosmosis?

Back

The electron transport chain in photosystem II.

Front

What happens to electrons after they reach photosystem I?

Back

They are energized by light and pass through a second electron transport chain.

Front

What is formed when electrons are passed through the second electron transport chain?

Back

Reduced NADP.

Front

What characterizes non-cyclic photophosphorylation?

Back

Electrons do not return to photosystem II.
