1
New cards
chloroplast
organelle in which photosynthesis occurs
2
New cards
Chlorophyll
green pigment in plants that absorbs light energy, embedded in the thylakoid membrane
3
New cards
Thylakoid
green disks found in chloroplasts and the site of the light reactions
4
New cards
stroma
aqueous fluid found inside the chloroplast and the site of the Calvin Cycle
5
New cards
Light reactions
Light energy is converted into chemical energy in the form of ATP and NADPH
6
New cards
Reactants of the Light Reactions
water and sunlight
7
New cards
Products of the Light Reactions
ATP, NADPH, oxygen
8
New cards
3 main phases of the Calvin Cycle
carbon fixation, reduction, regeneration of RuBP
9
New cards
Carbon Fixation (Calvin Cycle)
the enzyme Rubisco attaches CO2 to RuBP producing 3-PGA
10
New cards
Reduction (Calvin Cycle)
Energy from ATP & NAPDH is used to reduce 3-PGA to G3p
11
New cards
Regeneration of RuBP (Calvin Cycle)
Some G3P stays in the cycle to regenerate RuBP and the cycle continues
12
New cards
What is the final electron acceptor in the light reactions?
NADP+
13
New cards
What molecule provides electrons for the Light Reactions?
water
14
New cards
ATP synthase
enzyme in the light reactions that makes ATP as H+ ions diffuse through
15
New cards
What is produced in the light reactions that is used in the Calvin Cycle?
ATP & NADPH
16
New cards
Thylakoid space
Energy from the ETC is used to pump H+ here
