photosynthesis Flashcards
the membrane system of chloroplast consists of
grana
stromal lamellae
matrix
the membrane system is responsible for
trapping light and formation of ATP and NADPH
photosynthetic apparatus consists of
light and pigment
total pigments
250 to 400
eg of accessory pigments
chl a,b,c,d,e , carotenoids and phycobilins
essential pigments and accessory pigments take part in
e transfer rxn and energy transfer rxn resp
pigment organisation in bacteria and cyanobacteria
chromatophore and thylakoid lamellae
chlorophyl a is found in
all oxygenic photosynthesising organisms from cyanobacteria to higher plants
head and tail of chl a
magnesium porphyrin ring (hydrophilic) and phytol tail (hydrophobic )
chl a mol formula
C55H72O5N4Mg
chl b is found in
euglenoids,green algae and higher plants
mol for of chl b
c55h70o6n4mg
chl synthesis
succinyl CoA + glycine+ light and 2H
universal accessory pigment
carotenoids
lutein
