what produces carbs
carbon reactions
carbon reactions use what
CO2
carbon reactions produce what
sugars
in the carbon reactions, the chloroplast will use _____ produced in the light reactions
the ATP and NADPH
carbon reactions are also known as
the calvin cycle
calvin cycle assembles...
CO2 into glucose
how does the calvin cycle assemble CO2 into glucose?
carbon fixation
PGAL synthesis
RuBP regenerated
ATP and NADPH from light reactions provide what in the carbon reactions
potential energy and electrons
explain carbon fixation
CO2 combines w/ ribulose biphosphate (RuBP) to form 6 carbon product
catalyzed by RuBP carboxylase/oxygenase or rubisco
RuBP is...
5 carbon sugar
explain PGAL synthesis
6 carbon product breaks down into two 3-carbon molecules of phosphoglyceric acid (PGA)
in PGAL synthesis, after the 6 carbon product breaks down into two 3 carbon molecules of PGA, what happens
PGA is converted into PGAL (phosphoglyceraldehyde)
PGAL can be used to do what
to make more complex molecules like glucaose or sucrose -- some rearranged
explain RuBP regenerated
some PGAL rearranged to form RuBP
PGAL is what
a three carbon sugar
step 1 of carbon reactions
rubisco adds CO2 to RuBP
what is the product when rubisco adds CO2 to RuBP
an unstable 6 carbon molecule is produced
where do carbon reactions happen?
in the stroma
CO2 comes in the ______, reactions happen in the ________
stoma
stroma
step 2 of carbon reactions
ATP and NADPH from light reactions are cashed in
PGA is converted to PGAL
step 3 carbon reactions
one PGAL leaves and multiple PGALs combine to form glucose
