Water insoluble photosynthetic pigment:
Correct answer: A. Chlorophyll a
- A. Chlorophyll a
- B. Chlorophyll b
- C. Carotenoids
- D. All of these
Explanation
The correct answer is Chlorophyll a because it is a water-insoluble pigment that plays a central role in photosynthesis by capturing light energy. Chlorophyll b is more polar and not classified as water-insoluble, although it assists in capturing light. Carotenoids are water-insoluble but serve different roles in photosynthesis, such as photoprotection and accessory light absorption. Therefore, the statement 'All of these' is incorrect because not all listed options are water-insoluble.

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.
