Pick up the one called accessory pigments:
Correct answer: D. All of these
- A. Carotenes
- B. Chlorophyll b
- C. Xanthophylls
- D. All of these
Explanation
Accessory pigments are integral to photosynthesis, as they allow plants to capture a broader spectrum of light wavelengths than chlorophyll a alone can absorb. Carotenes and xanthophylls are types of carotenoids that absorb light in regions that chlorophyll a does not, while chlorophyll b helps extend the light absorption spectrum. Thus, the correct answer is 'All of these' because all listed options are accessory pigments. Options A, B, and C are incorrect individually because each represents only a part of the full range of accessory pigments.

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.
