The excess energy is absorbed by three carotenoids molecules such as violaxanthin, antheraxanthin, and zeaxanthin, which of the following statements correct about these molecules?

#Unit 6. System Physiology – Plant
  1. Both of the aromatic rings of violaxanthin have a bound oxygen atom while antheraxanthin only one of the two rings has a bound oxygen and in zeaxanthin neither does
  2. Zeaxanthin is the least effective of the three xanthophylls molecules in heat dissipation
  3. the level of zeaxanthin remains relatively constant throughout the day
  4. the antheraxanthin content increases at high PPFD and decreases at low PPFD
