Photosynthesis Chapter Review

Energy is released from ATP when

• ATP is exposed to sunlight

• adenine bonds to ribose

• a phosphate group is added

• a phosphate group is removed

A granum is a

• stack of chloroplasts

• membrane enclosing a thylakoid

• photosynthetic pigment molecule

• stack of thylakoids

The light dependent reaction occurs in the

• chloroplast

• thylakoid membrane

• stroma

• stomata

What are the products of the light-dependent reactions?

• oxygen gas

• ATP

• NADPH

• all of the above

What are the reactants of photosynthesis. SELECT ALL THAT APPLY:

• water

• oxygen

• glucose

• carbon dioxide

If you continue to increase the intensity of light that a plant receives, what happens?

• The rate of photosynthesis increase with light intensity.

• The rate of photosynthesis decreases with light intensity.

• The rate of photosynthesis does not change.

• The rate of photosynthesis increases and then levels off.

If carbon dioxide is removed from a plant's environment, what would you expect to happen to its production of high-energy sugars?

• No sugars would be produced.

• Carbon dioxide does not affect the production of high energy sugars in plants.

• More sugars would be produced.

• The same number of sugars will be produced but without carbon dioxide.

What is the beginning step of photosynthesis?

• Pigments in photosystem II absorb light.

• pigments in photosystem I absorb light.

• ATP synthase allows H+ ions to pass through the thylakoid membrane

• High-energy electrons move through the electron transport chain.

The light collecting units of a chloroplast are the 

• electron carriers

• stroma

• photosystems

• high-energy sugars

The light independent reaction (Calvin cycle) occurs in the

• chloroplast

• thylakoid membrane

• stroma

• stomata
