Photosynthesis

Calvin Benson Cycle
Light independent: occurs in stroma
-Passes ability to absorb atmospheric gasses (CO₂)
-One carbon is taken from CO₂, and attaches it to RUBP ribulusebis phosphate (a 5 carbon molecule) to form a 6 carbon intermediate molecule. This is called carbon fixation.
This happens 6 times, to make 12 PGA's. Then when you energise with ATP, and NADPH. H⁺ bonds to PGA, and it takes those e^- to form PGAL. You have 12 PGAL, but you only need 2 to form glucose, and the remaining 10 will be rearranged to form 6 RuBP.
-The 6-carbon molecule is unstable, and breaks in 1/2 to form PGA- phospho glycerate
-The PGA is energized with ATP and NADPH, and turns into PGAL.
-This PGAL bonds with another PGAL to form phosphorilated glucose.
-10 PGAL are then rearranged to make six 5 carbon RUBP, and the process restarts.

~light phase- takes in sun, water (osmosis), and produces O₂, ATP, and NADPH.
~dark phase- takes in ATP, NADPH, CO₂, and releases water, glucose, ADP and P (ATP reduced to original form) and NADP⁺ (H was used for photosynthesis).
PGAL = phospho gluteraltohide
