what are the main organs of photosynthesis
leaves
CO2 and O2 enter/exit where
through the stomata
leaf _______ contains chloroplasts
mesophyll
organelle of photosynthesis
chloroplasts
mesophyll cells are located where?
each leaves
each mesophyll cell contains what
several chloroplasts
pore=
stoma
difference between stoma and stroma
stoma - pore
stRoma - inside the cell
pigment molecules are embedded in...
thylakoid membrane
pigment in the ______ _______ capture ______
thylakoid membrane - sunlight
a large protein structure in the thylakoid membrane
a photosystem
pigment molecules, such as chlorophyll, are embedded in______
photosystems
why does life depend on photosynthesis
-feeds plants
-provides energy and raw materials for other organisms
-waste product oxygen essential to life
pigments are 1. protein 2. carb 3. lipid 4. nucleic acid
lipid
light reactions occur where
thylakoid membranes
light reactions do wat
covert solar energy to chemical energy
energy from captured photons are used to
create ATP
energy from captured photons are used to
create ATP
carbon reactions occur where
in stroma
carbon reactions are also called
light-independent reactions
carbon reactions also called
calvin cycle
___ and _____ used to reduce ___ to _______
ATP - NADPH - CO2 - glucose
solar energy =
electromagnetic light
unit w/ chorophyll a and other pigment molecules and proteins anchored in the thylakoid membrane
photosystem
chlorophyll a molecule that uses the light energy
reaction center
other pigments that capture energy and funnel it to reaction center
antenna pigments
organization enhances _____
efficiency
fuzzy colors inside thalykoid membrane
light reactions
photosystem 1 range
reaction center P700-700nm
photosystem 2 range
P680-680nm
photosystems are connected by
electron transport chain
which photosystem produces ATP
2
as electrons pass along ETC, the energy they lose drives...
transport of protons from the stroma into the thylakoid space
photosystem II process
pigment absorbs light energy
transferred to reaction center
excites pair of electrons
ejected and grabbed by first protein in ETC linking photosystems
lost electrons replaced by splitting water
O2 is a waste product
when electrons are passd along ETC, the _____________________
proton conentration increases
enzyme that uses gradient to produce ATP
ATP synthase
ATP synthase is like what
a dam generating electricity
what begins photosynthesis
light reactions
light reactions produce what
ATP and NADPH
what is a byproduct of photosynthesis
O2
