The pigment that appears yellow-green in the chromatogram is
Open in App
Solution
The correct option is C Chlorophyll b
The correct option is C.
Explanation of the correct option:
- One kind of chlorophyll is chlorophyll b which is yellow-green in color.
- Chlorophyll b is the primary accessory pigment, however, there are other carotenoids, xanthophyll, anthocyanin, phycoerythrin, and phycocyanin as additional accessory pigments.
- By absorbing light energy, chlorophyll b aids in photosynthesis. Because of its carbonyl group, it dissolves better in polar liquids than chlorophyll a.
- In contrast to chlorophyll a, which has a methyl group (-CH 3), chlorophyll b has an aldehydic group (-CHO) in the second ring. Every chlorophyll molecule has a lengthy phytol tail that is connected to it by an ester bond.
Explanation of the incorrect options:
Option A:
- Chlorophyll is the main pigment of photosynthesis for the vast majority of organisms that are capable of it (plants, cyanobacteria, and algae).
- The energy needed for future photosynthetic processes is obtained by it by absorbing light in the orange to red and violet to blue spectrums.
Option B:
- Many of the yellow, orange and red colors of flowers, fruits, and vegetables are produced by a group of carotenoid pigments called xanthophylls, which contain oxygen.
- Xanthophylls can serve as supplemental light-harvesting pigments, as LHC structural components, and as chemicals necessary for shielding photosynthetic organisms from light's potentially hazardous effects.
Option D:
- More than 750 naturally occurring pigments belonging to the family of carotenoids are produced by plants, algae, and photosynthetic microorganisms.
- Many plants get their yellow, orange, and red hues from these vibrant chemicals. The majority of the 40 to 50 carotenoids contained in the human diet are found in fruits and vegetables.
Final answer: The pigment that appears yellow-green in the chromatogram is chlorophyll b.
