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. The absorbance of radiant energy by Melanin pigment in the skin. b. 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. 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 by increasing the temperature.

Write a question appropriate for this study guide about the heat energy added to 1683 grams ofany biological substance whose specific heat capacity is given in the OpenStax College Physicstextbook, if its temperature changes by 0.018 degrees Celsius. Then answer it.
Despite the thermal stability of covalent bonds in physiological systems, some of these bonds are sensitive to energy input from external sources. The molecule can absorb heat from the environment without changing its chemical structure, as will occur when there is a local temperature increase. 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 physiological process is example to this? Select one : a. Absorbance of light by 11-cis-retinal. b. Translucent to opaque conversion of egg whites after cooking. C. Absorbance of light by melanın. d. a & b e. a & c f.b&c g. a, b & c

A 75 kg person doing light work requires about 3000 kcal of food energy perday, 40% of which is actually used by the body’s cells. (The other 60% is lostas heat and in waste products.) Before being used by the cells, effectively allof this energy is stored in ATP, which is then cleaved into ADP and PO3−2 , with the release of 12.5 kcal per mole of ATP.(a) How many moles of ATP are turned over per day in this fashion? Whatmass of ATP does this correspond to? (The molecular weight of ATP is507 g/mol.)(b) The body actually contains approximately 5 g ATP. Estimate the averagerecycle time for an ATP molecule. You see that it is much more efficientto reuse ADP rather than to synthesize it de novo (from scratch).
