Photosynthesis
Light Reaction
Requires sunlight
Dark Reaction
Occurs in thylakoid of chloroplast
Does not require sunlight
Produces ATP and NADPH
Occurs in Stroma
Photosystem II
Absorbs sunlight
Water molecules are broken down
Energy ions get transferred across membrane.
Hydrogen ions are transported across thylakoid membrane
Photosystem I
Energy is absorbed from sunlight
NADPH is produced
Hydrogen ions diffuse through protein channel
ADP is changed into ATP when hydrogen ions flow through ATP synthase.
Builds glucose
Called Calvin cycle
Used to make simple sugars
Requires Co2
Water molecules are broken down :
Used to run light in-dependent reaction
