50 Cards in this Set

  • Front
  • Back
eat things that trap living light
consumer
high energy, big molecules
glucose
composed of an adenosine molecule with 3 phosphate groups attached, high energy
ATP
low ATP or energy
ADP
cells need energy to
make new molecules
to build cell parts/membranes or organelles cells need
energy
maintaining homeostatis requires
energy from cells
movement of ions across membrane (active transport)
requires energy
cells need energy for
eliminating waste
movement of cilia or cellular contractions require
energy
process plants use to trap the sun's energy and build carbohydrates that store energy
photosynthesis
producer
autotroph
use chemicals to make food
chemosynthetic
consumers, eat autotrophs and heterotrophs
heterotroph
black absorbs
all colors
chlorophyll is contained in the
granum
thylakoid membrane
chlorophyll
stroma is
fluid
chlorophyll A, Chlorophyll B, Xanthophyll, Carotenes, Anthocyanin
plant pigments
bright green, yellow green, yellow, faint yellow, red
accessory pigments
chlorophyll A is
the first to break down in the fall
we find chlorophyll in the chloroplasts of
green plants,algae and in the membranes in the cytoplasm of photosynthetic bacteria
reflected colors
are what we see
if we see red
the leaf is using every color but red
absorbed colors are used in
photosynthesis
chlorophyll reflects
green and some yellow wavelengths of light and absorbs the energy of other colors
energy of the sun is trapped in chloroplasts
photosynthesis
light energy is converted to chemical energy and stored
photosynthesis
need h^2O and CO^2 for this to happen
photosynthesis
light's converted to chemical reactions
light-dependent reactions ( light reactions)
h^2O is split
hydrogen and an energy source for the Calvin cycle/photolysis
o^2 is given off
photolysis
series of reactions that form simple sugars using CO^2 and hydrogen from the photosynthesis
calvin cycle
splitting of water to replace the electron
photolysis
carries the excited electron and combines with a hydrogen ion and becomes NADPH
carrier/NADP+
rubisco
takes carbon dioxide and fixes it
requires chloroplast structure, chlorophyll, light energy,CO^2 and H^2O
photosynthesis
produces PGAL(simple sugar)then later 2 PGAl then 1 glucose
photosynthesis
light captured by chlorophyll loses electron
step 1
water is split to replace electrons, O^2 is released (waste product)
step 2
electron energy is transferred to ATP +P e- energy--> ATp
step 3
ATP and NADPH represent light energy in the form of chemical energy; provide E in dark rxns
step 4
CO^2 is taken in; fed into Calvin Cycle
step 5
CO^2 is combined with 5-C sugar by enzyme rubisco; makes temporary 6-C compound; breaks down into 3-C sugars(PGA); changed into 2 PGAL
step 6
3x around cycle, put in 3CO^2; make one net PGAL ( simple 3-C sugar)
step 7
since 3CO^2 has less energy than PGAL, must add in energy(ATP and NADPH)from light rxns
step8
add 2 PGAL to 1 glucose in later reactions
step 9
occuring constantly
photosynthesis
many pigments are embedded in phtosynthetic
photosynthesis
membranes of chloroplasts; act as light antennae
photosynthesis
