In antenna complexes, how is energy transferred among the pigment molecules?

a. photophosphorylation

b. redox reactions

c. fluorescence

d. resonance

Expert Solution & Answer

Summary Introduction

Introduction:

Antenna complexes, also known as the light-harvesting complexes, are protein and pigment complexes present in thylakoid membrane of plants that transfer the electrons to the electron acceptor at the photosynthetic reaction center.

Answer to Problem 1TYK

Correct answer:

By resonance the energy is transferred among the pigment molecules in the antenna complexes.

Explanation of Solution

Explanation/Justification for the correct answer:

Option (d) is given that resonance. The light-sensitive molecules are also called chromophores. The antenna complex pigments absorb the photons from the incoming solar radiation, which then transfers the associated energy to the nearby chlorophyll molecule. This results in the excitation of another electron. Hence, option (d) is correct.

Explanation for incorrect answers:

Option (a) is given as heat. The heat energy from the incoming solar radiation is not absorbed by the chromophore molecule (antenna complex); thus, it cannot transfer the heat energy for the excitation of the electron in the chlorophyll. So, it is a wrong answer.

Option (b) is given as redox reactions. The redox reactions involve the transfer of energy by the transfer of the electrons. So, it is a wrong answer.

Option (c) is given as fluorescence. and the fluorescence energy transfer involves the transfer of the light energy, it is not responsible for the excitation of the electron in the chlorophyll as a result of the transfer of energy from the antenna complex. So, it is a wrong answer.

Hence, options (a), (b), and (c) are incorrect.

Conclusion

Thus, it can be concluded that the mechanism of transfer of the energy among the molecules that are light sensitive is referred to as resonance or fluorescence resonance energy transfer.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
