FINAL photosynthesis/energy Flashcards
sunlight arrives at a plant in units of energy called
photons
why are plants green
reflect green wavelengths of light
stroma
central fluid filled space containing DNA RNA ribosomes of chloroplast
grana
stack of thylakoid membrane structures
what part of the electromagnetic spectrum is used for photosynthesis
visible light
where do light dependent reactions occur
thylakoid membrane
products of the light reactions of photosynthesis
NADPH ATP O2
products of dark reaction of photosynthesis
organic molecules
first law of thermodynamics
energy is neither created nor destroyed
second law of thermodynamics
energy is partly lost as heat in the process of recycling
wavelengths of visible light
380-720 nm
C3 plants
cant store, 3 carbon atoms
C4 plants
store CO2 in 4 carbon molecules
CAM plants
crassulacean acid metabolism; stores lots of CO2 in various molecules
what green pigment traps sunlight during photosynthesis
chlorophyll
what chloroplast structure is the site of photosynthesis
stroma and thylakoid membrane
organelle involved in cellular respiration
mitochondria
product of glycolysis
pyruvate and ATP
glycolysis = how many ATP molecules
2
what gas is released during the transition reaction
CO2
how many molecules of ATP does the electron transport system yield
30-32
the activated carrier molecule which transforms phosphate bonds
ATP
the activated carrier molecules which transfers high energy electrons
NADH NADPH
activated carrier molecule that transfers high energy acetyl groups
Acetyl CoA
G
free energy
Delta G
change in energy
10 to 20 (favorable vs unfavorable)
unfavorable
molecule that pyruvate is converted to in anaerobic cellular respiration (yeast and plant cells)
alcohol
molecule that pyruvate is converted to in anaerobic cellular respiration (animal and bacteria cells)
lactic acid
what type of reactions is NADH involved in
cellular respiration
type of reactions NADPH is involved in
photosynthesis
what ion is responsible for turning the ATP synthase pump to generate ATP during electron transport
hydrogen
who won nobel prize for discovery of the dark reaction
melvin calvin
who won nobel prize for the discovery of the citric acid cycle
Krebs
the critical factor driving yeast to use fermentation to metabolize sugar is
lack of oxygen
first process in breaking down glucose is
glycolysis
which process produces alcohol or lactate
fermentation
what pair of processes are aerobic
krebs cycle and electron transport system
what process occurs in the cytosol
glycolysis
what process occurs in the mitochondria
krebs cycle
entropy
the disorder created by heat in a reaction
oxidation
lose an electron
reduction
gains an electron
