The Calvin Cycle the dark reaction

The Calvin Cycle (the dark reaction)
2
The Calvin Cycle

• Light not required
• Location Stroma
• End Result Glucose (and other 6C sugars) will be
  created by ATP, H ions, and CO2

3
Steps of the Calvin Cycle

• 1) CO2 will combine with a RuBP (5C molecule) to
  create a 6C molecule
• RuBP Ribulose Biphosphate
• 2) 6C molecule quickly breaks down PGAL (two 3C
  sugar)
• PGAL Phosphoglyeraldehyde
• ATP and H provide the energy
• 3)Once PGAL (3C sugar) is created
• Some PGAL will bond to create glucose
• Some PGAL will create RuBP to start the cycle over
