  • Photosynthesis
    • Structure
      • Grana
        • set of thylakoids
      • Stroma
        • filled with fluid
      • Intermembrane space
    • Light Dependent Stage
      • Takes place in thylakoids
      • requires light and water
      • Chlorophyll absorbs light and electrons become excited.
        • Electrons leave chlorophyll and go to electron carrier which is reduced.
          • Electrons lose energy at each stage of electron carriers.
            • Energy is used to combine Pi and ADP.
    • Light independent Stage (Calvin cycle)
      • Takes place in stroma
      • Is dependent upon ATP produced in light dependent
      • 1C
        • RuBP
          • 5C
            • 2x triose phosphate
              • Glucose
          • Rubisco
          • 2x Glycerate 3-phosphate
            • 2x triose phosphate
              • Glucose
            • 2 ATP + 2 rNADP
    • Limiting factors
      • Light intensity
      • Carbon dioxide concentration
      • Temperature
  • 2x Glycerate 3-phosphate
    • 2 ATP + 2 rNADP
