photosynthesis

• light-dependent（in granum）
  • definition
    • It need light. Turning ADP and NADP+ into ATP and NADPH by using sunlight energy and water Oxygen is a byproject of this process.
  • detailed information
    • Absorbs light energy and create high-energy electrons. Meanwhile splitting water molecules and releasing H+ ions and oxygen.
    • Many electron carrier proteins shuttle high-energy electrons during ATP-generating reactions.
    • Electrons are reenergized and second electron transport chain transfers electrons to NADP+, NADPH is produced by that .
    • The difference between concentration of charge and H+ ion across the membrane provides the energy to make ATP.
• right one is dependent and left one is independent

• light-independent reaction.(in stroma)
  • definition
    • It do not need light. Turning ATP, NADPH and carbon dioxide into glucose
  • detailed information
    • Produces 12 3-carbon compounds by combine six carbon dioxide molecules in the atmosphere with six five carbon molecules.
    • Turning energy from ATP and high-energy electrons from NADPH into higher-energy forms by using the 3-carbon molecules.
• what is photosynthesis
  • Convert sunlight, water and carbon dioxide into glucose and oxygen
• factors that affect Photosynthesis
  • Light intensity
  • temperature
  • availability of water
• how the light-dependent reaction and light-independent reaction are linked to each other
  • Light-dependent reaction produce ATP and NADPH. Light-independent reaction need the products from light-independent reaction to produce glucose.
• formula
  • Sunlight+Water+Carbon Dioxide→Oxygen+Glucose
