Photosynthesis occurs in 2 major reactions. The first is the _______ __________ .

The first reaction in photosynthesis requires the reactant ______ as well as energy from the _____ .

• H20, sun

• H20, ATP

• CO2, sun

• CO2, ATP

Select all of the products of the first reaction of photosynthesis.

• ATP, NADPH, and CO2

• ATP, NADH, and O2

• CO2 and C6H12O6

• NAD+ and O2

The products from the first photosynthesis reaction are then used for the light ________ reaction.

What is the pigment used for capturing energy from the sun to be used during photosynthesis?

Which best describes the electron transport chain?

• An enzyme that creates ATP from the phosphorylation of ADP

• An energy molecule that donates electrons during the Calvin Cycle

• A series of carrier molecules that transport electrons in the thylakoid membrane & capture energy

• An enzyme in the thylakoid membrane and stroma that fixes carbon during the Calvin Cycle

Which factor(s) would affect the rate of photosynthesis? (select ALL that apply)

• carbon dioxide concentration

• oxygen concentration

• light intensity

• temperature

• chlorophyll levels
