Light Dependent

The little packets of light energy are called

• rays
• photons
• electrons
• radiant energy

The chlorophyll in the chloroplast is found in the

• stroma
• matrix
• photosystems
• cristae

The light dependent reaction begins with 

• photosystem I
• photosystem II
• electron carriers
• electron acceptors

What does an electron being "excited" mean?

• It has been released from a water molecule
• It has lost energy.
• It has gained energy.
• It has been accepted by an electron carrier.

The electrons from photosystem II are replaced by

• the electrons from hydrogen ions
• electrons from Photosystem I
• a carbon dioxide molecule splitting
• a water molecule splitting

The splitting of a water molecule is called

• photons
• photolysis
• oxidation
• reduction

As electrons move from PS II to PS I, they 

• gain energy
• lose energy

The H+ concentration gradient is used to 

• make NADPH
• split a water molecule
• generate ATP
• form water

Where do the electrons in PS I come from?

• PS II
• the H+ moved across the thylakoid membrane
• the formation of NADPH

Where is the NADP found that is used to make NADPH?

• the thylakoid membrane
• the thylakoid space (lumen)
• the stroma
• the reaction center
