Inside a Chloroplast
 Photosynthesis takes place inside ______________________
 ________________are saclike photosynthetic membranes inside the chloroplast
 ________________ are stacks of thylakoids
 Proteins in the thylakoids membrane organize pigments (chlorophyll) into clusters
called _____________________
 Scientist describe reactions of photosystems in two parts:
  ________________________________________________
   Takes place in the _________________ membrane
  ________________________________________________ (Calvin Cycle)
   Takes place in the _________________
Light-Dependent Reactions
•  The light-dependent reactions produce O2 gas and ___________ ADP and NADP+
into energy carriers ATP and NADPH
•  Takes place in the photosystems in the _________________________
 Photosynthesis _____________ when pigments in photosystem II absorbs light
 The electron transport chain _____________photosystems II and photosystem I
 The light-dependent reactions produce ATP that is used in the ________________
Calvin Cycle
 Also called the _________________________ Cycle
 The Calvin cycle uses ATP and NADPH from the light- dependent cycle to produce
high-energy _________________
 The Calvin cycle uses _________________ from the atmosphere to make sugars
