The molecule can absorb heat from the environment without changing its chemical structure, as will occur when there is a local temperature increase. The molecule will have a higher energy. If the increase in energy is above KT (i.e., the entire environment has not increased its temperature), the molecule will come to thermal equilibrium with the environment around it, and return to its original energy state. Which one of the following is example to this? Select one: a. Conversion of 11-cis form of retinal to the all-trans form of retinal upon exposure to light, with a maximum absorbance at 500 nm. b. The absorbance of radiant energy by Melanin pigment in the skin. c. Thymine-thymine and thymine-cytosine pyrimidine bridges formation upon exposure of DNA to UV-B radiation. d. The translucent to opaque conversion of egg whites when cooked

The molecule can absorb heat from the environment without changing its chemical structure, as will occur when there is a local temperature increase. The molecule will have a higher energy. If the increase in energy is above KT (i.e., the entire environment has not increased its temperature), the molecule will come to thermal equilibrium with the environment around it, and return to its original energy state. Which one of the following is example to this?
Select one:
a. Conversion of 11-cis form of retinal to the all-trans form of retinal upon exposure to light, with a maximum absorbance at 500 nm.
b. The absorbance of radiant energy by Melanin pigment in the skin.
c. Thymine-thymine and thymine-cytosine pyrimidine bridges formation upon exposure of DNA to UV-B radiation.
