- Describe how thermodynamics and metabolism are related.what is free Gibbs energy and write the expression of free energy change. Define the exergonic and endergonic processes.The role of an enzyme in an enzyme-catalyzed reaction is to make the reaction more thermodynamically favorable. True or False
- Discuss the following statement: “enzymes and heat are alike in that both can speed up reactions that—although thermodynamically feasible—do not occur at an appreciable rate because they require a high activation energy. diseases that seem to benefit from the careful application of heat—in the form of hot chicken soup, for example—are therefore likely to be due to the insufficient function of an enzyme.”Describe how thermodynamics and metabolic are relateState the first and second laws of thermodynamics, and discuss the implications of these laws as they relate to organisms.
- Describe the induced-fit model of enzyme activity. *Which of the following statements is most directly described by the first law of thermodynamics? A B с D The synthesis of highly-ordered biomolecules is coupled with the production of heat energy. All energy-transferring processes involve the loss of some of that energy into an unus- able form. Enzymes reduce the activation energy of chemical energy by stabilizing substrates at their transition states. The energy for the synthesis of glucose is provided by the absorption of light energy in chlorophyll pigments.1) Which of the following statements is true for the Second Law of Thermodynamics? a) ΔS (Sfinal-Sinitial) for the system is negative. b) The living system is not exchanging heat nor matter. c) Energy is conserved in the universe. d) The biological system never reach equilibrium.
