1) Where does the energy trapped by Chlorophyll go during the light-dependent reactions of photosynthesis?
A) It stays in the bonds of the pigment molecules.
B) It is immediately trapped in sugars.
C) It is mostly transferred to ATP and high-energy electrons in NADPH.
D) It is released as heat.
2) What was the lightest and least polar of the molecules separated in the chromatography exercise last week?
A) xanthophyll.
B) Chlorophyll b.
C) Chlorophyll a.
D) carotenes.
3) DCPIP worked to do what in last week's photosynthesis experiments?
A) It served as an electron acceptor, taking electrons from the Calvin Cycle.
B) It served as an electron donor, giving up electrons to the light-dependent reactions.
C) It served as an electron acceptor, taking electrons from the light-dependent reactions.
D) It served as an electron donor, giving up electrons to the Calvin Cycle.
E) It served as a pigment, transferring absorbed light energy to the light-dependent reactions.
4) Photosynthesis is an extremely important reaction because it creates the energy that is used to make sugar molecules.
True
False
5) The pigments in last week's chromatography exercise could be pulled off of the paper and moved up the paper column because they were soluble in the non-polar solvent (petroleum ether) that was used as a carrier, and the pigment molecules are mostly non-polar lipid-soluble molecules.
True
False
