3) to produce ATP and NADPH

4)  stroma of the chloroplast

5)  red and yellow

6)  excite electrons.

7)  harvest photons and transfer light energy to the reaction-center chlorophyll

8)  this pigment is best at absorbing light with a wavelength of 700 nm.

9)  carbon dioxide is incorporated into PGA.

10)  to test for liberation of O2 in the light.

11) ATP and NADPH

12)  ATP

13)  the synthesis of ATP

14) establishment of a proton gradient

 15) thylakoid membrane ---inner mitochondrial membrane

16)  the stroma to the thylakoid space.

17)  thylakoid membranes of chloroplasts

35)  CO₂ and O₂  

36)   C₄ plant.

37)  They use PEP carboxylase to initially fix CO₂.

38)  fix CO₂ into organic acids during the night.

39)  3-phosphoglycerate molecules 

40) RuBP.

41)  ATP and NADPH.

42)  H₂O à NADPH  à Calvin cycle

43)  reduction of NADP⁺.

44)  In both cases, an enzyme other than rubisco carries out the first step in carbon fixation.

45)  release of oxygen

46)  The splitting of water molecules provides a source of electrons. --Chlorophyll (and other pigments) absorb light energy, which excites electrons. --ATP is generated by photophosphorylation.

47) The P680 chlorophyll donates a pair of protons to NADPH, which is thus converted to NADP+.

48)  Bacteria congregated in these areas because these areas had the most oxygen being released.

49) the relationship between wavelengths of light and the oxygen released during photosynthesis.

50)  The bacteria would be relatively evenly distributed along the algal filaments.

52) Other pigments absorb light in addition to chlorophyll a.

53)  420 mm
