Lab 6 Results Flashcards
gamma ray
small wavelength and high frequency
radio
very big wavelength and low frequency
what is the relationship between wavelength and frequency
inversely related
what do frequency and wavelength products produce
a constant known as the speed of light
is radio wavelength safe
yes; wifi/cell phone signal
is gamma ray safe
no
- x-ray
what is electro medically radiation composed of
photons
what is the relationship between photon and frequency
energy of 1 photon is proportionate to 1 frequency
how does a photon behave with high frequency
high energy photon
1st law
energy cannot be created or destroyed
2nd law
- can never reach absolute 0
- entropy of universe can only increase
what would happen if the wrong color was absorbed in a plant
photosynthesis would be low in efficiency
what colors do plants absorb best
red and blue color
what is the proper equation for photosynthesis that biologists use
6CO2+12H2O+light—>C6H12O6+6O2+6H2O
why do biologists use the specific equation of photosynthesis
all the O2 should come from water only
what photosynthesis equation do chemists use and why do they prefer that equation
6CO2+6H2O+light—>C6H12O6+6O2
- so it’s balanced correctly
what is the main issue with the chemist equation
don’t have enough water molecules; equation implies some O2 comes from CO2 which is incorrect
matrix
is stroma
where do the light reactions occur
thylakoid
what happens in the thylakoid
photosystem 1 and 2
- PSII or P680
- PSI or P700
what do the numbers represent in P680 and P700
P680 (photosystem 2)
- wavelength it absorbs best)
P700 (photosystem 1)
- wavelength it absorbs best)
PSII
- water is split and release O2
- get electrons from water
- electrons get excited from sunlight
what does the ETC allow
calms electrons down
how is ATP produced
H+ ions will move down through process of chemiosmosis and ATP synthase to produce ATP
How do H+ ions move
from high to low concentration
what type of energy is glucose
chemical
what type of energy is sunlight
solar
how is NADPH produce
electron gets picked up by NADP+ and produce NADPH
where does the calvin cycle occur
stroma
what does calvin cycle take to work
3CO2
6NADPH
9ATP
what does the calvin cycle produce
1 molecule of G3P
T-test
- 2 sets of data
- is average of 2 data the same or diff
what does the p value tell you in a t-test
change in average are similar or not
what must the p value be in order to reject hypothesis
smaller than 50%
what was the purpose of using a CO2 sensor
photosynthesis uses CO2 but lab also didn’t have good O2 readers
did you observe the light reaction, calvin cycle, or both
calvin cycle because we were measuring CO2
why did we use different colors of transparency
trying to filter the light and see affect of different color of light
did you observe any difference with different levels of transparency
we should have seen low efficiency with green color and high efficiency with blue and red color
