All living organisms require energy from the surrounding and utilized by
biomolecules that mediates the flow of energy from exergonic reactions to the energy
requiring processes of life. This unit deals with the energy behind life in the form of
three laws of thermodynamics. Derived the mathematical equations for the laws.
Comparison of thermodynamic parameters like ΔH or ΔS and ΔG have been done to
provide meaning ful insights about a process and its use in calculating the relative
contributions of molecular phenomena to an overall process.
