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

a. by heat

b. by redox reactions

c. by fluorescence

d. by 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.

Explanation of Solution

Explanation/Justification for the correct answer:

Option (d) is given by 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 by 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 and the fluorescence energy transfer involves the transfer of the light energy. So, it is a wrong answer.

Option (c) is given as fluorescence. Furthermore, 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

The mechanism of transfer of the energy among the molecules that are light sensitive is referred to as resonance or fluorescence resonance energy transfer.

You have returned to college to become a phylogeneticist. One of the first things you wish to do is determine how mammals, birds, and reptiles are related. Like any good scientist, you need to consider all available data objectively and without a preconceived “correct” answer. In pursuit of that, you should produce a phylogenetic tree based only on morphological features that show birds and mammals are more closely related. You will then produce a totally different tree, also using morphological features, that shows birds and reptiles are more closely related. Do not forget to include all three groups in both your trees. Based solely off the trees you produce, which relationship would you consider the more likely and why? Once you have answered that question, provide a brief summary of the “modern” understanding of the relationship between these three groups.

true or false, the reason geckos can walk on walls is hydrogen bonding between their foot pads and the moisture on the wall.

Biology laboratory problem Please help. thank you You have 20 ul of DNA solution and 6X DNA loading buffer solution. You have to mix your DNA solution and DNA loading buffer before load DNA in an agarose gel. The concentration of the DNA loading buffer must be 1X in the DNA and DNA-loading buffer mixture after you mix them. For that, I will add _____ ul of 6X loading buffer to the 20 ul DNA solution.
