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
|
