on the wild side Flashcards
photosynthesis involves reduction of
carbondioxide to carbohydrate
carbohydrates can be used to provide energy for
respiration
hydrogen for respiration comes from
splitting of the water by light
waste oxygen is released to
atmosphere
6CO2 + 6H20
C6H12O6 + 6O2
Splitting of water by light is called
photolysis
the energy for photolysis is trapped by
pigment called photolysis
energy for photolysis is
trapped by a pigment called photolysis
light dependent reactions
in this process, a pair of electrons from chlorophyll is boosted to a higher energy level by the light energy it has trapped.Here they are accepted by an electron acceptor and then passed along a chain of carriers.energy released is used to convert adp and inorganic phosphate.the electrons then enter another chlorophyll molecule.the electrons then enter another chlorophyll molecule.the electron then enter another chlorophyll molecule,The electron eventually passes to NADP wuth the hydrogen from whater to form reduced NADP.The ATP and reduced NADP are then used in light dependent reactions to make carbohydrate from carbondioxide.
occurs in thylakoid
the light dependent reactions make
ATP and Reduced NADP which are then used in the light dependent reactions
another name for light independent
calvin cycle
5 C molecules Rubp combines with co2
catalyzed by
unstable 6 carbon compound
RUBISCO
6 C compound immediately splits into
2 molecules of 3 C compound called Gp
gets energy from
Atp converted to adp and phosphate and reduced NADPH
reduced nadp and atp coverts GP to
GALP
galp goes in series and
either becomes RuBp or some will change into glucose
co2 is fixated in
calvin cycle
ATP provides energy for
chemical reaction in cell
when energy is needed
,phosphate is removed from atp to give adp and phosphate
the energy is released when
phosphate forms bonds with water
ATP is also used widely as
a way of transferring energy
ATP is an intermdeiate between
energy producing reaction and those that need energy
some of the glucose made in calvin cycle
is used by the plant in respiration.the rest is used to synthesise all the molecules on which the plant relies
molecules on which the plant relies
simple sugar polysacharide amino acid lipid nucleic acid
