Transcript Calvin Cycle - West Branch Schools

To sum it up…
Light dependent reactions use:
water, ADP, NADP+
Light dependent reactions produce:
oxygen, ATP, NADPH
ATP and NADPH provide energy to build
high energy sugars.
The Calvin Cycle (in Stroma)
Uses
ATP and NADPH from
light dependent reactions to
make high energy sugars
Does NOT need light
(light independent)
6 CO2 molecules enter cycle from the air
and combine with six 5-carbon molecules
 The twelve 3-C molecules are converted to
higher energy forms
 Where does this energy come from?


2 of the 3-C molecules are removed from
the cycle to make sugars, lipids, amino
acids and other cmpds needed by plant
 The
ten 3-C molecules left are turned
back into six 5-C molecules
 They combine with 6 new CO2 and
begin next cycle
To Sum it up…
The Calvin Cycle uses CO2 to produce
one 6-C sugar
