no
- x-ray

Question 7

what is electro medically radiation composed of

Answer 7

photons

Question 8

what is the relationship between photon and frequency

Answer 8

energy of 1 photon is proportionate to 1 frequency

Question 9

how does a photon behave with high frequency

Answer 9

high energy photon

Question 10

1st law

Answer 10

energy cannot be created or destroyed

Question 11

2nd law

Answer 11

• can never reach absolute 0
• entropy of universe can only increase

Question 12

what would happen if the wrong color was absorbed in a plant

Answer 12

photosynthesis would be low in efficiency

Question 13

what colors do plants absorb best

Answer 13

red and blue color

Question 14

what is the proper equation for photosynthesis that biologists use

Answer 14

6CO2+12H2O+light—>C6H12O6+6O2+6H2O

Question 15

why do biologists use the specific equation of photosynthesis

Answer 15

all the O2 should come from water only

Question 16

what photosynthesis equation do chemists use and why do they prefer that equation

Answer 16

6CO2+6H2O+light—>C6H12O6+6O2
- so it’s balanced correctly

Question 17

what is the main issue with the chemist equation

Answer 17

don’t have enough water molecules; equation implies some O2 comes from CO2 which is incorrect

Question 18

matrix

Answer 18

is stroma

Question 19

where do the light reactions occur

Answer 19

thylakoid

Question 20

what happens in the thylakoid

Answer 20

photosystem 1 and 2
- PSII or P680
- PSI or P700

Question 21

what do the numbers represent in P680 and P700

Answer 21

P680 (photosystem 2)
- wavelength it absorbs best)

P700 (photosystem 1)
- wavelength it absorbs best)

Question 22

PSII

Answer 22

• water is split and release O2
• get electrons from water
• electrons get excited from sunlight

Question 23

what does the ETC allow

Answer 23

calms electrons down

Question 24

how is ATP produced

Answer 24

H+ ions will move down through process of chemiosmosis and ATP synthase to produce ATP

Question 25

How do H+ ions move

Answer 25

from high to low concentration

Question 26

what type of energy is glucose

Answer 26

chemical

Question 27

what type of energy is sunlight

Answer 27

solar

Question 28

how is NADPH produce

Answer 28

electron gets picked up by NADP+ and produce NADPH

Question 29

where does the calvin cycle occur

Answer 29

stroma

Question 30

what does calvin cycle take to work

Answer 30

3CO2
6NADPH
9ATP

Question 31

what does the calvin cycle produce

Answer 31

1 molecule of G3P

Question 32

T-test

Answer 32

• 2 sets of data
• is average of 2 data the same or diff

Question 33

what does the p value tell you in a t-test

Answer 33

change in average are similar or not

Question 34

what must the p value be in order to reject hypothesis

Answer 34

smaller than 50%

Question 35

what was the purpose of using a CO2 sensor

Answer 35

photosynthesis uses CO2 but lab also didn’t have good O2 readers

Question 36

did you observe the light reaction, calvin cycle, or both

Answer 36

calvin cycle because we were measuring CO2

Question 37

why did we use different colors of transparency

Answer 37

trying to filter the light and see affect of different color of light

Question 38

did you observe any difference with different levels of transparency

Answer 38

we should have seen low efficiency with green color and high efficiency with blue and red color
