Light independent reaction (Dark Reaction)
No description yet. This curated deck is ready for daily study.
Card preview (19)
When there is an enough amount of ATP and NADPH of the chloroplast (6 of each molecule), the energy of these molecules can be used to..
Synthesize Glucose
Light independent is also known as..
The Calvin cycle
Light independent reaction may occur in the absence of light because..
It does not require on the excitation of electrons to initiate any reactions
Light independent take place during..
The day
The light independent reactions involve three essential steps..
Carbon dioxide fixation, Activation and reduction and Replacement of RuBP
In Carbon dioxide fixation, six CO2 molecules require to…
Initiate cycle
In Carbon dioxide fixation, the carbon atom in each CO2..
Binds to a molecule of RuBP in the Stroma via an enzyme called Rubisco
In Carbon dioxide fixation, the resulting compound is..
High energy but very unstable
In Carbon dioxide fixation, the resulting compound also breaks down into..
2 identical 3-carbon compound also known as PGA
In Carbon dioxide fixation, PGA is..
Stable but low energy
CO2 + RuBP –> unstable C6 –> 2 C3
CO2 + RuBP –> unstable C6 –> 2 C3
In activation and reduction, the PGA are activated by.. to form PGAL
ATP and reduced by NADPH
In activation and reduction, PGAL is..
High energy in its reduced state
In activation and reduction, some PGAL leaves the cycle and may be used to make..
Glucose
After PGAL leaves the cycle, the remaining PGAL..
Continues the cycle
In the replacement of RuBP, the energy from ATP is used to..
Break down and reform PGAL into RuBP so the cycle can begin again
CO2 + H2O + Light energy –> C6H12O6 + O2 - O2 is required to..
Begin Calvin cycle
CO2 + H2O + Light energy –> C6H12O6 + O2 - C6H12O6 is produced by..
PGAL that leave the chloroplast
The Calvin cycle takes place in..
the Stroma
