chapter 7 Flashcards
what carries out photosynthesis
plants, algae, bacteria, and other protists
where does photosynthesis occur
The 2 outer membranes
What 2 outer membranes does photosynthesis occur in
internal compartment (Stroma) and the internal membrane (thylakoid membrane)
how does photosynthesis make energy
uses light energy, carbon dioxide, and water to produce food
what are the 2 reactions in photosynthesis
light dependent reaction and light independent reaction
what’s the simplified reaction for photosynthesis
6Co2 + 6h20 — C6H12O6 + 6O2
sunlight has ___ type of light
(1 type) white light
shorter wavelengths equal
Higher (more) energy
all colors have _____ wavelengths
different
what do the pigment molecules in the thylakoid membranes do
absorb energy of specific colors of light.
chlorophylls do not absorb what type of light
green
claroteids do not absorb what type of light
yellow orange and red light
photosystem 11
absorbs sunlight energy
where is the photosystem 11 located
in the thylakoid membrane
what does the water splitting enzyme do
breaks water molecules down, extracts the electrons, and feeds them back into p680 which makes oxygen, protons, and neutrons.
electrons lose a little _____ each transfer
energy
Plastoquinone(Pq)
transporting electrons from photosystem II to the cytochrome b6f complex
Plastocyanin(Pc)
mediates electron transfer
Pq uses energy from the electron to
pump H+ to generate a proton gradient
Pc system passes electrons to
photosystem 1 (ps 1)
Ps 1
absorbs sunlight
Fd passes electrons to
NADP+ which then results in reducing NADP+ to NADPH
What is the NADPH used for after the Fd process
It used in the Calvin Cycle
