Photosynthesis

STUDY
PLAY
photosynthesis
light energy converted to chemical bond energy and carbon fixed as organic compound; CO2 water and light make glucose water and oxygen
light dependent reactions
use light to make ATP and power light independent
light independent reactions
calvin cycle which produces sugar
photosynthetic pigments
different types absorb different wavelengths of light incoming to the cell
grana
pancake stacks in chloroplast where light reactions occur
stroma
space inside chloroplast where light independent reactions occur
thykaloids
pancakes where photosystems I and II are
photosystems
light harvesting centers in thykaloids
noncyclic photophosphorylation
one type of light reaction; ATP and NADPH are formed; light goes to PSII (P680) and releases oxygen by splitting water, ATP is produced; energy absorbed by PHI(P700) and NADPH produced for Calvin cycle
cyclic photophosphorylation
only produces ATP (not oxygen or NADPH) electrons transported in cycle from P680 to P700 and then back again
calvin cycle
light independent; produces sugar PGAL; uses ATP and NADPH from light reactions to fixate carbon in reduction reaction
photolysis
process where water is split in noncyclic photophosphorylation to produce oxygen
