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
