Photosynthesis

Question 1

what is photosynthesis?

Answer 1

1. capturing energy from sunlight
2. using the energy to make ATP and reducing in the form of NADPH
3. using the ATP and NADPH to synthesize organic molecules from CO2

Question 2

what is the light reaction

Answer 2

make ATP and NADPH

Question 3

what is the dark reaction(light independent)

Answer 3

turning CO2 into glucose

Question 4

what is the equation for photosynthesis

Answer 4

6CO2 + 12 H2O + light —> C6H12O6 + 6CO2

Question 5

what membranes do chloroplast have

Answer 5

inner and outer

Question 6

what are stroms

Answer 6

water filled space within chloroplast

Question 7

what are thylakoids

Answer 7

filled with chlorophyll inside a chloroplast “pancake”

-where light reaction occurs

Question 8

what are granium

Answer 8

“stack of pancakes” stack of thylakoids

Question 9

what is photophosphorylation

Answer 9

water split into O2

Question 10

calivn benson cycle is also known as

Answer 10

the dark reaction

Question 11

the energy in a photon is inverse to wavelength

Answer 11

lots of energy=short wavelength

less energy=long wavelength

Question 12

pigments do what?

Answer 12

absorb light

Question 13

chlorophyll “A”

Answer 13

main photosynthetic pigment

Question 14

chlorophyll “B”

Answer 14

accessory pigment- shift the graph left

Question 15

what do caratenoids do

Answer 15

assist by capturing energy from wavelengths not absorbed– blue and green

Question 16

light reactions

Answer 16

1. primary photoevent
2. electron transport(ATP)
3. chemiosmosis

Question 17

photosystem 2- 10 transmembrane protein subunits

Answer 17

water is split to release 4 electrons and 4H+

Question 18

photosystem 1

Answer 18

makes NADPH on the stromal side

Question 19

dark reaction

Answer 19

carbon fixation happens in the stroma

Question 20

the calvin cycle

Answer 20

• rubulose biophosphate carboxlase(RuBO)
• most abundant protein in life
• 3 molecules/second (slow reaction)
• uses reverse of glycolysis(puts sugar together)
