In paper chromatography xanthophyll will give _ color:
Correct answer: C. Yellow
- A. Orange
- B. Grey
- C. Yellow
- D. Blue-Green
- E. Yellow-Green
Explanation
In paper chromatography, xanthophylls are pigments that are often responsible for giving a yellow color. Xanthophylls are a type of carotenoid pigment found in plants, and they contribute to the yellow, orange, and red colors in various plant tissues. In paper chromatography, these pigments can be separated based on their different affinities for the paper and the mobile solvent. During paper chromatography, a sample containing xanthophylls is spotted onto a piece of filter paper. As the solvent travels up the paper, it carries the pigments along with it. Xanthophylls, being yellow pigments, will manifest as yellow bands or spots on the paper when the chromatography is complete.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
