b) When the water molecules present in the cells are split by the energy from the sunlight
c) Oxygen isn't a product of photosynthesis, it's a reactant
d) It's made by ATP synthase, an enzyme specific to the production of oxygen

Where does the light dependent reaction take place in the chloroplast?

b) Glucose and ATP
c) Water and carbon dioxide

The energy transformation that occurs during the light dependent reaction is...
a) Chemical to solar
b) Solar to chemical
c) Mechanical to nuclear
d) Chemical to mechanical

What role does NADPH play in the process of photosynthesis?
a) It is an energy molecule, delivering energy from the light dependent reaction to the light independent reaction.
b) It does not play a role in photosynthesis.
c) It is an electron taxi, delivering electrons from the light dependent reaction to the light independent reaction
d) It's the polymer molecule that plants store excess glucose as

The enzyme that makes ATP during the light dependent reaction is called...
a) ATP synthase
b) ATP synthose
c) ATP productase
d) ATP productose

The light independent reaction is also known as..
a) The Coolidge Cycle
b) The Creeper Cycle
c) The Hobbes Cycle
d) The Calvin Cycle

What starts the Calvin Cycle?
a) Water
b) Sunlight
c) Carbon dioxide
d) Glucose

Where does the Calvin Cycle occur?
a) In the thylakoid membrane
b) In the stroma
c) In the stomata
d) In the mitochondria

What is the main pigment inside the chloroplast that absorbs the light energy to start the process of photosynthesis?
a) Chlorophyll
b) Carotenoids
c) Xanthophyll
d) Beta-carotene

Why are plants green?
a) All the chlorophyll pigments inside the plants are green, so the plants appear green.
b) The chlorophyll pigments absorb all other wavelengths of light except green.
c) Carotenoids reflect the green wavelength
d) Xanthophylls reflect the green wavelength

Plants use the energy of the sun to make food. What is their food molecule?
a) Sucrose
b) Lactose
c) Fructose
d) Glucose

a) Heterotrophs
b) Autotrophs
c) Evil
d) Smart

The correct equation for photosynthesis is...
a) 6 CO2 + 6 H2O -- O2 + C6H12O6
b) 6 C6H12O6 + 6 CO2 -- 6 O2 + 6 H2O

a) ATP synthase
b) Electron transport protein cycle
c) Electron transport chain
d) Electron train

The H+ ions made from the splitting of the water molecule are used by...
a) ATP synthase to make ATP
b) NADPH to pick up electrons
c) the chlorophyll pigment to reflect green light
d) the thylakoids to make oxygen
