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.

A negligence action was brought by a mother against a hospital on behalf of her minor daughter. It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth. Did a patient relationship with the transfusing hospital exist?
