9 Chloroplast

10 Photosynthesis A

11 Photosynthesis B

12 Photosynthesis chemical reaction (Remember… conservation of matter.) 6 CO2 + 6 H2O C6H12O6 + 6 O2 + Heat

13 Fig: 10.6

14 LE 10-8a White light Refracting prism Chlorophyll solution Photoelectric tube Galvanometer The high transmittance (low absorption) reading indicates that chlorophyll absorbs very little green light. Green light Slit moves to pass light of selected wavelength 0 100

15 LE 10-8b White light Refracting prism Chlorophyll solution Photoelectric tube The low transmittance (high absorption) reading indicates that chlorophyll absorbs most blue light. Blue light Slit moves to pass light of selected wavelength 0 100

16 Absorption vs. Reflection

17 Fig: 10.9a and b

18 Fig: (How many electrons are in Mgs outer shell?) Hint: Look at the Periodic Table.

19 Answer: 2 Those 2 electrons will leave Mg and enter into the Electron Transport Chain.

20 Photosystem and collecting sunlight energy.

21 Photosystems 1 and 2

22 Fig: Where it is occurring.

23 Non-cyclic electron flow

24 Cyclic electron flow

25 Pumping the H+ (protons) into a CONFINED space to BUILD UP POTENTIAL energy.

26 See the H+

27 Turning Potential energy into Kinetic energy to make ATP

28 Fig: step 1

29 Fig: Step 2

30 Fig: step 3
