There are Two Main Stages of Photosynthesis Reactions:
1. Light dependent reactions - Require light energy
2. Light independent reactions - Do Not Require Light Energy
Light Dependent Reactions
* Light energy is needed
*Water are needed
* Occur in the chlorophyll filled thylakoid membrane
* Produce molecules that provide energy to Light Independent Rxns
(ATP and NADPH - High Energy molecules)
* Waste byproduct is Oxygen
Basic Steps of the Light Dependent Reactions
1. Light energy “excites” the electrons in the chlorophyll molecule
2. These “excited”, high energy electrons are passed from one
protein molecule to another along the electron transport chain in
the thylakoid membrane and are picked up by two molecules:
NADP to form NADPH High Energy molecules needed to power the Light Independent Rxns
ADP to form ATP
3. Enzymes split the water molecule: H2O
2H+ + 2e- + O* The 2e- replace the electrons the chlorophyll molecule lost
* Oxygen gas is released
Light Independent Reactions (Calvin Cycle)
* Do NOT require light energy – can happen in dark conditions
* Requires ATP and NADPH made in light rxns as energy source
* Occurs in the stroma fluid
* CO2 needed. CO2 enters through the leaf stomata.
* Glucose molecules made. #1 Job
Basic Steps of the Light Independent Reactions (Calvin Cycle)
1. CO2 molecules diffuse across the stroma.
2. CO2 is rearranged using H+ and Energy from ATP and NADPH
to make glucose. Carbon gets ”fixed” into organic compounds.
