An absorption spectrum of chlorophylls has:

Correct answer: A. Two peaks and one valley

  • A. Two peaks and one valley
  • B. One peak and one valley
  • C. Two peaks and two valleys
  • D. One peak and two valleys

Explanation

The most accurate representation of the absorption spectrum of chlorophylls is two peaks and one valley. The two peaks indicate strong absorption in the blue and red regions of the visible spectrum, while the single valley in the green region explains the green color of plants. This pattern reflects the efficiency of chlorophyll pigments in capturing light energy for photosynthesis while reflecting green light.

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.
