4.3 Photosynthesis in Detail KEY CONCEPT Photosynthesis converts light energy is captured and used to build sugars that store chemical energy.

4.3 Photosynthesis in Detail

The equation for the overall process is: 6CO 2 + 6H 2 O  C 6 H 12 O 6 + 6O 2 C 6 H 12 O 6 granum (stack of thylakoids) thylakoid sunlight 1 six-carbon sugar 6H 2 O 6CO 2 6O 2 chloroplast energy stroma (fluid outside the thylakoids)

4.3 Photosynthesis in Detail Photosynthesis in plants occurs in chloroplasts. Photosynthesis occurs in a series of stages in the chloroplasts. –grana (thylakoids)- photosystem II, photosystem I and the electron transport chain. –Stroma- Calvin Cycle chloroplast stroma grana (thylakoids)

4.3 Photosynthesis in Detail The first stage of photosynthesis captures and transfers energy. The light-dependent reactions include groups of molecules called photosystems.

4.3 Photosynthesis in Detail Photosystem II captures and transfers energy. 1.chlorophyll absorbs energy from sunlight –energized electrons enter electron transport chain 2.water molecules are split –oxygen is released as waste 3.hydrogen ions are transported across thylakoid membrane

4.3 Photosynthesis in Detail Photosystem I captures energy and produces energy- carrying molecules. 4.chlorophyll absorbs energy from sunlight 5.energized electrons are used to make NADPH –NADPH is transferred to light-independent reactions

4.3 Photosynthesis in Detail The light-dependent reactions produce ATP. 6.hydrogen ions flow through a channel in the thylakoid membrane 7.ATP synthase attached to the channel makes ATP

4.3 Photosynthesis in Detail

Light-independent reactions occur in the stroma and use CO 2 molecules enter the Calvin cycle The second stage of photosynthesis uses energy from the first stage to make sugars.

4.3 Photosynthesis in Detail The light-independent reactions make sugars. –take place in stroma –needs carbon dioxide from atmosphere –use energy to build a sugar in a cycle of chemical reactions

4.3 Photosynthesis in Detail A molecule of glucose is formed as it stores some of the energy captured from sunlight. 1.carbon dioxide molecules enter the Calvin cycle 2.energy is added and carbon molecules are rearranged 3.a high-energy three-carbon molecule leaves the cycle

4.3 Photosynthesis in Detail 4.two three-carbon molecules bond to form a sugar – remaining molecules stay in the cycle A molecule of glucose is formed as it stores some of the energy captured from sunlight.
