Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings AN OVERVIEW OF PHOTOSYNTHESIS 7.1 Autotrophs - the producers of - produce their - produce the food supply for

Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings 7.2 Photosynthesis - occurs in - occurs primarily in - ____ enters and ____ exits - through ____________________

Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings Chloroplast structure – Stroma Location of – Thylakoids Contain

Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings 7.3 Plants produce - by splitting - the O 2 given off by photosynthesis is made from

Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings 7.4 Photosynthesis occurs in two stages linked by ATP and NADPH Light reactions – Occur in – Convert light energy to chemical energy as – Produce O 2 as a Calvin cycle – Occurs in – Assembles sugar molecules from CO 2 using ATP and NADPH energy from

THE LIGHT REACTIONS: CONVERTING SOLAR ENERGY TO CHEMICAL ENERGY 7.5 Sunlight is - electromagnetic - radiation travels as - the distance between waves = Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings

Thylakoids of the - contain several - absorb some - reflect Chlorophyll a - reflects Chlorophyll b - reflects Carotenoids -

Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings 7.6 Photosystems capture When a pigment molecule absorbs energy: – an electron is raised in energy from – it then rapidly drops back to – the electron releases excess – some pigments also

Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings 7.7 In the light reactions, electron transport chains generate Photosystem II – A pigment molecule – The excited electrons are passed to an - providing energy to - water is ____________, releasing ___

Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings Photosystem I – energy is – excites an electron of _____________ which - passes through an

Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings THE CALVIN CYCLE: CONVERTING CO 2 TO SUGARS 7.8 The Calvin Cycle makes – Inputs carbon from energy from – Output organic
