Chlorophylls mainly absorb light of which wavelength?
Correct answer: D. Orange red
- A. Red blue
- B. Yellow orange
- C. Violet red
- D. Orange red
Explanation
Chlorophyll mainly absorbs violet-blue and orange-red wavelengths. Green, yellow and indigo are least absorbed and are transmitted or reflected by chlorophyll, although yellow are often masked by darker green color. That's why plants appear green.

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.
