Light ReactionsLight dependent reactions take place in the thylakoid membrane, with the pigment chlorophyll absorbing sunlight
Light Reactions1. Energy from sunlight breaks water into H+, oxygen (O2) and electrons (e-).
Light Reactions2. H+ and e- are used to produce energy carrying molecules NADPH and ATP
Light Independent ReactionsLight independent reactions occur in the stroma
The Calvin (C3) Cycle
The Calvin (C3) Cycle
CO2 enters the leaf through the stomates
The Calvin (C3) Cycle
ATP and NADPH (from the light reactions) power the creation of three carbon chains
The Calvin (C3) Cycle
ADP and NADP+ return to the light reactionsin the thylakoid to be “recharged”
Formation of Glucose3-carbon chains from the C3 cycle join to form the six carbon molecule, glucose (or other molecules required by the plant)C-C-C + C-C-C C-C-C-C-C-C
