Exercise 4. Questions: What is the pattern of absorption of the different pigmen

Question

Exercise 4. Questions: What is the pattern of absorption of the different pigments at different wavelengths of light? How does wavelength influence absorption for different pigments? Hypothesis: Prediction: Results: Fill out the table below with the wavelengths corresponding to the peak and valley of absorption for each pigment. Table 3. Summary of the wavelength ranges that were maximally and minimally absorbed. Predicted absorption peaks Maximum Wavelength(s) of Wavelength(s) of Minimum absorption (nm) absorption (nm) Chlorophyll1 A Chlorophyll B Xanthophyll Beta carotene Graph (Insert your figure showing the absorption spectra of the spinach pigments): Figure 1. write caption here Explanation of results:

Explanation / Answer

The wavelengths-

Plants capture light energy and use this energy and convert it to sugars by photosynthesis. In photosynthesis, the first step is light absorption which is carried by specialized molecules called pigments and photoreceptors. Each of these pigments absorbs and respond to a different wavelength of lights depending on the photosynthetic reaction center present in it and the photoreceptor.

pigment predicted absorption peaks (nm) wavelength of maximum absorption(nm) wavelength of minimum absorption (nm) Chlorophyll A 430 nm 420 nm 720 Chlorophyll B 450 nm 460 700, 720 Xanthophyll 435 nm 420 680, 700, 720,580 Beta carotene 450 nm 460 640,660,680,700,720
