Light Dependent Reaction

• Needs
• Light
• Water
• ADP
• NADP
• Pigments
• Thylakoid membranes of the chloroplast

• Products
• ATP
• NADPH
• oxygen

6
The Process
Chlorophyll and other pigments take in light and
H2O. They strip off the protons and release
Oxygen. The H (protons) are used to turn ADP
into ATP. The electrons are used to turn NADP
into NADPH

Light Independent Reactions

• Process
• C o2 enters the stomates of the leaf and the
  stroma of the chloroplast
• It binds with RuBP using Rubisco enzyme to make
  PGAL.
• Energy comes from ATP and NADPH
• PGAL combines with more carbon to make sugar

9
Calvin Cycle/Light Independent

• Needs
• NADPH
• ATP
• CO2
• Stroma of chloroplast

• Product
• Glucose and other organic compounds
