Which one is not correct about chlorophyll b?
Correct answer: D. It is the primary pigment in photosynthesis
- A. It acts as an accessory pigment
- B. It reflects green light
- C. It absorbs light mainly in the blue and red regions
- D. It is the primary pigment in photosynthesis
Explanation
Chlorophyll b acts as an accessory pigment, helping chlorophyll a by capturing additional light energy and transferring it for use in photosynthesis. It reflects green light, which gives plants their green color, as it mainly absorbs light from other parts of the spectrum. This pigment is most effective in absorbing light from the blue and red regions, allowing plants to utilize a wider range of light for photosynthesis. However, chlorophyll b is not the primary pigment in this process. The main pigment responsible for capturing light energy and driving the reactions of photosynthesis is chlorophyll a, making the statement that chlorophyll b is the primary pigment incorrect.

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.
