Use the absorpion specira to answer the questions The peak absorption for chiorophyllb is close to this wavelength so we can predict that biue ignt would be effecive o The graph ndicates that chiorophyl a absorbs very litte tbue lignt, so we can predct that blue would not be effeclve An instrument caled a spectrophotometer measures the relative rnounts of light of different wavelengths absorbed by a soluton of a pigment An abcorption spectrum graphs the results oblained rom a rpectrophotomeler In the absoption spectra graphed below, the three My Answers Gp Submit show the absorption of various wavelengths of äght by the piuments chiorophyll a,chiorophyll b, and carotenoids Use the graph to answer the questions to the ngt Part F An action spectrum plots the rate of phososynthesis at various wavelengms of visible light, and a Chloro- shows that blue light with a wavelength of about 490 nm is efflective in driving photosynthesis. Based on this information and the absorption spectra shown at let what role mrychlorornya band carotenoids play in photosynthesis? Carotenoids These pigments probably pay onty a photoprotectve role (atsorting encess kgtt energr Iha could damage chiorophyl &) and a role in producing the colors of fat follage 600 Because chlorophylla is round in the reaction carter comple, oth photostere l and, can assume mat these other pigmsnts plsy no role in photosynthests Wavelength of light (rnm) These pigments are able to absorb more weveengths of lignt (and thus move energ, then chio ophyl a aone can absod As parr of ight harvesang camereses in prototy sisams me brosden the range at sghc that can be used in the ignt teactons
