Xanthophylls protect chlorophyll-a from ___
1 Photo-reduction
2 Photo-respiration
3 Photo-oxidation

BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS
337429
Which of the following is the major pigment responsible for trapping light?
1 Xanthophyll
2 Chlorophyll
3 Carotenoid
4 All of these
Explanation:
Chlorophyll is the major pigment responsible for trapping light.
BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS
337430
Chlorophyll is suited for the capture of light energy because
1 Certain wavelengths of light raise it to an excited state.
2 In its excited state chlorophyll gives off electrons.
3 Chlorophyll's structure allows it to attach to thylakoid membranes.
4 All of the above.
Explanation:
The "tails" of chlorophyll molecules are associated with the thylakoid membranes of the chloroplasts. When excited by light, the chlorophyll moves into an excited state and passes electrons to acceptor molecules. This begins to set up the proton gradient across the membrane that will drive ATP synthesis.
