Series of electron carrier proteins that shuttle high-energy electrons during ATP-generating reactions
NADP+
Light-independent
Light-dependent
Electron transport chains
Light-independent reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugar
Stroma
ATP synthase
Calvin Cycle
Electron Transport Chains
Fluid portion of the chloroplast; outside of the thylakoids
Chlorophyll
Stroma
ATP
NADP+
Set of reactions in photosynthesis that do not require light; energy from ATP and NADPH is used to build high-energy compounds such as sugar; also called the Calvin Cycle
Light-dependent
Light-independent
Electron transport chain
ATP synthase
Main products of the Calvin Cycle
Oxygen, NADP+, ADP
Glucose, CO2, ADP
ADP, NADP+, Glucose
ATP, NADPH, Oxygen
The Calvin Cycle occurs in the
Thylakoid
Grana
Inner membrane of chloroplast
Stroma
5 carbon sugar that combines with CO2 in the Calvin Cycle
3-PGA
G3P
RuBP
Glucose
Tiny pores on the underside of leaves
Stroma
Stomata
Thylakoids
Chloroplasts
Plants can close their stomata when the temperature is hot
To prevent water loss
To prevent loss of oxygen
To prevent loss of carbon dioxide
To bring in more carbon dioxide
Which of the following is a way to increase the rate of photosynthesis?
Increase oxygen levels
Decrease CO2 levels
Increase light intensity
Decrease water level
Which of the following is true of the Calvin Cycle?
carbon dioxide and energy (ATP and NADPH) are used to make organic compounds
energy is absorbed from sunlight and converted to chemical energy stored in ATP and NADPH
Occurs in the thylakoid
Occurs in the cytoplasm
Rate of photosynthesis ________ as light intensity _________
increases, increases
decreases, increases
increases, decreases
Increasing carbon dioxide can increase photosynthesis, but only to a maximum rate because
There are not enough RuBP molecules
Oxygen cannot leave fast enough
Large amounts of CO2 cannot fit in the chloroplast
Calvin cycle can only go as fast as the light reactions
Temperatures that are too high can slow photosynthesis because
stomata stay open
enzymes are ruined
there is not enough CO2
there is too much water
Which of the following is NOT a reactant of the light independent reactions?
NADPH
ATP
Oxygen
Carbon dioxide
To bring in nonliving carbon (CO2) and use it to make organic compounds is a process called _______________.
carbon fixiation
cellular respiration
light reaction
fermentation
