Biology - Photosynthesis

  • Photosynthesis
    • uses energy to turn CO2 + H2O into glucose + O2
      • Glucose = sugar for respiration
      • Endothermic reaction
    • Limimiting Factors
      • Light intensity
        • Greater = increase rate (up until certain point where something else is limiting factor)
      • Temp.
        • [Effects all chem. reactions]
        • Greater = faster rate
          • BUT photo. is catalysed by enzymes (work at optimum temp.)
      • CO2 conc.
        • One of reactants
          • Greater = increase rate (up until certain point where something else is limiting factor)
      • Can be limiting factor
        • More chloroplast = more energy absorbed = increase rate
    • Chloroplast
      • Green pigment that absorb light energy for photosynthesis
        • Can be limiting factor
          • More chloroplast = more energy absorbed = increase rate
