Structure and details of photosynthesis

• Equation


  6CO2 + 6H2O → C6H12O6 + 6O2
• Glucose production

  • made by plants themselves
  • energy is stored in glucose
• Involves coenzymes

  • aids the function of an enzyme, usually by transferring a chemical group from one molecule to another
  • NADP -transfers hydrogen between molecules
• Photosystems


  • where light energy is absorbed for the LDR
  • light harvesting system - absorbs a range of wavelengths, transfers energy to the reaction centre
  • reaction centre - contains CHLOROPHYLL A, where electrons are excited during the LDR
• Photosystem

  Pigments and proteins

  A) light harvesting system

  B) reaction centre

  C) A

  D) accessory

  
• Chloroplasts

  - small, flattened organelles

  A) thylakoid

  B) double

  C) 70s

  D) DNA

• Pigment

  CHLOROPHYLL A IS A PRIMARY PIGMENT, THE REST ARE ACCESSORY

  • chlorophyll A - blue/green
  • chlorophyll B - yellow/green
  • carotene - orange
  • xanthophyll - yellow
  • phaetophytin - grey
  • anthocyanin - red/purple
