Students have asked these similar questions
what is the first and 2nd law of thermodynamics? define and what are the implications of those laws?
Within biological systems, there are always reactions that seem to occur when thermodynamically, they should not. An example is in the process of glycolysis (the conversion of glucose to pyruvate) which has ΔG°' = 2183.6 kJ/mol. How is glycolysis possible with such a large, positive ΔG°', when cells are governed by the laws of thermodynamics?
Can the thermodynamic property Δ G° be used to predict the speed of a reaction in a living organism? Why or why not?

- 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.arrow_forwardThe first and second laws of thermodynamics are useful for biochemists who investigate chemical reactions in living organisms.
