Which one of the following is not of carotenoids?

Correct answer: A. Convert light energy into chemical energy

  • A. Convert light energy into chemical energy
  • B. Protect chlorophyll
  • C. Transfer energy
  • D. Protect human eye

Explanation

Transfer of energy, broadening the spectrum, protection of chlorophyll molecules and eyes are the functions of carotcnoids. The conversion of light energy into chemical energy is the function of chlorophyll molecules. In chloroplasts, the responsibility of converting light energy into chemical energy lies with the photosystems. The photosystems are protein complexes embedded in the thylakoid membrane of the chloroplasts.

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.
