Calvin Cycle Flashcards
Calvin cycle or also known as?
Light independent reaction
Calvin cycle is named after who?
Melvin Calvin
Others might call it Calvin-Benson cycle, to include the name of the other scientist. What was the name of the other scientist?
Andrew Benson
the chemical process that helps to
convert potential energy from
ATP and NADPH into potential
energy stored in ____ ?
Glucose
If light dependent reaction occurs in thylakoid, where does the calvin cycle takes place?
Stroma
Carbon enters the Calvin cycle in
the form of ___ and leaves in the
form of ___.
CO2 and Sugar
What are the 3 phases of calvin cycle?
Carbon fixation
Reduction
Regeneration of RuBP
During carbon fixation, carbon dioxide from the atmosphere is
attached to _____ , a 5-
carbon molecule.
And the enzyme that catalyzes this
first step is ____
Ribulose
bisphosphate (RuBP),
Rubisco (Ribulose biphosphate carboxylase-oxygenase)
The product of the reaction is a
six-carbon intermediate that is
short-lived because it is so _____that it
immediately splits in half,
forming two molecules of
3-phosphoglycerate (for each
CO2 fixed).
energetically unstable
Each turn of the cycle
involves only ___ RuBP
and ___ carbon dioxide and
forms two molecules of
3-PGA
one
Each molecule of
3-phosphoglycerate receives an
additional phosphate group from
ATP, becoming
____?
1,3-bisphosphoglycerate.
1,3-bisphosphoglycerate, which
also loses a phosphate group in the
process, becoming ___
glyceraldehyde
3-phosphate (G3P).
For every three molecules of
CO2 that enter the cycle, there
are ____ of G3P
formed.
six molecules
One of the three-carbon
molecules of G3P leaves the
cycle to become a part of a ____ molecule
carbohydrate
Other five molecules must be
recycled to regenerate the
_____ molecules of RuBP.
three
