Biological Thermodynamics Assignment Help
Biological thermodynamics is the quantitative study of the energy transductions that occur in and between structures, living organism and cells and of the function and nature of the chemical processes underlying these transductions. Biological thermodynamics address the question that the benefit associated with any particular phenotypic trait is worth the energy investment it requires. German-British biochemist and medical doctor Hans Krebs' in 1957 book Energy Transformation in Living Matter, that was written with Hans Kornberg was the first major publication on the thermodynamics of biochemical reactions. The Non-equilibrium thermodynamics has been applied to explain how biological organisms can develop from disorder. Ilya Prigogine also developed the methods for the thermodynamic treatment of such systems. As these systemsare formed and maintained by the dissipative processes that exchange energy betweenthe system and its environment, he called this system as dissipative system. If that exchange ceases they disappear. In biology, the energy transformation is dependent upon photosynthesis.
in biology - In biology and biochemistry
, the field of biological thermodynamics is focused on principles of thermodynamics. The Principles covered include the Gibbs free energy
, reaction kinetics, first law of thermodynamics
, the second law of thermodynamics
, statistical thermodynamics,and on hypotheses of the origin of life. The biological thermodynamics concerns itself with the study of biochemical dynamics such as: ATP hydrolysis,DNA binding, protein stability, enzyme kinetics, membrane diffusion, and other such essential energy controlled pathways.
The sun is the principal source of energy for living organism. Organisms like humans acquire indirect energy from the sun whereas, living organism like plants require direct sunlight. No matter what the type of living species, all living organisms must transduce, capture, store, and use energy to live.
There are two laws of thermodynamics-
The First Law of Thermodynamics
is a statement of the conservation of energy; however it can be changed from one form to another, energy can be neither destroyed nor created. A principle called Hess's Law arises from the first law. It states that the heat evolved or absorbed in a given reaction must always be independent of the manner and constant in which the reaction takes place.
The Second Law
is primarily concerned with whether or not a given process is possible. It states that no natural process can occur unless it is accompanied by an increase in the entropy of the universe
