Pick up the one(s) called as accessory pigments:

Correct answer: D. All of these

  • A. Carotenes
  • B. Chlorophylls
  • C. Xanthophylls
  • D. All of these

Explanation

Yes, carotenoids,xanthophylls and chlorophylls are accessory pigments. Accessory pigments are pigments that are not directly involved in the light-dependent reactions of photosynthesis, but they help to absorb light energy and transfer it to chlorophyll a, which is the primary pigment involved in photosynthesis. Carotenoids are yellow, orange, and red pigments that are found in plants, algae, and some bacteria. They absorb light energy in the blue and violet regions of the spectrum, which chlorophyll a does not absorb as well. This allows carotenoids to broaden the range of wavelengths that can be used for photosynthesis.Xanthophylls are yellow and orange pigments that are also found in plants, algae, and some bacteria. They absorb light energy in the blue-green and yellow-orange regions of the spectrum. This allows xanthophylls to absorb light that chlorophyll a and carotenoids cannot absorb, which helps to extend the range of wavelengths that can be used for photosynthesis. Chlorophylls are accessory pigments. Accessory pigments are pigments that help to absorb light energy and transfer it to chlorophyll a, which is the primary pigment involved in photosynthesis. Chlorophyll a is the most abundant pigment in plants and algae. It absorbs light in the blue-green and red regions of the spectrum. However, it cannot absorb all of the light that is available in the environment. This is where accessory pigments come in.

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.
