AP Photosynthesis Review: Light dependant and calvin cycle

What is the primary goal of photosynthesis?

• To absorb sunlight

• To make glucose and transfer light energy into chemical energy

• To release oxygen

• To consume carbon dioxide

Once a plant absorbs sun energy it need to convert it into chemical energy. Where would it store that chemical energy

• In the bonds of water

• in the bonds of ADP and NADP+

• in the bonds of NADH and FADH2

• in the bonds of ATP and NADPH

Where does the light-dependent reaction of photosynthesis take place?

• Cytoplasm

• Chloroplast stroma

• Thylakoid membrane

• Mitochondria

True or false: Water, Sunlight, NADP+ and ADP are inputs of light-dependent reactions?

• True

• False

What are the 3 reactants of the calvin cycle? (2 are the intermediate products of light dependent rxn)

• Glucose, NADPH, ATP

• Oxygen, NADPH, ADP

• NADPH, ATP, CO2

• Carbon dioxide, NADP+, ATP

What is the first step in the light-dependent reactions of photosynthesis?

• Formation of glucose

• Absorption of sunlight by pigments

• Transfer of electrons through the Electron Transport Chain

• Reduction of NADP+ to NADPH

Why are the Redox reactions of photosynthesis important? (select 2)

• Because they help in the storage of CO2

• Because they help in the breakdown of glucose in the calvin cycle

• So that CO2 can be reduced into glucose in the calvin cycle

• So that water can be oxidized into oxygen in the light dependent rxn

What is the role of CO2 in the Calvin cycle?

• It is a byproduct of the Calvin cycle

• It is used to create oxygen

• It donates carbon to RuBP which helps make glucose

• It is not involved in the Calvin cycle

True or False?

All organisms depend on photosynthesis weather directly or indirectly

• TRUE

• FALSE
