The Important Role Of Metabolism In Organisms

Metabolism has been an important part of life since the very beginning and is one of the many processes that distinguishes living things from any other forms on earth. This takes place when a cellular organisms use certain temperatures from inside one 's body to begin the process in which the metabolic courses will happen. Metabolism can be categorized into two separate categories in which organisms use the given pathways to build or break down different types of molecules in order for them to become useful for the individual organisms and those around them. These include catabolism and anabolism. Catabolism is known as the breakdown and oxidation, through chemical reactions, of larger molecules which yields the energy needed for anabolism…show more content…
Along with energy released during the exergonic reaction is the amount of energy given off in the form of heat that is used by the cell to increase its temperature naturally. This can also be known as an exothermic reaction in which the chemical reaction produces heat from the energy released. These processes of catabolism are the driving force for cellular respiration and digestion of food molecules (Catabolic 2013). Anabolism is the process in which macromolecules are made through biosynthesis from smaller molecular units. This reaction takes place when the energy of catabolic mechanisms is gained to carry out the chemical reactions in which energy is needed to be absorbed by the cells in order to form larger molecules from smaller ones. These molecules later become known as macromolecules. The process in which anabolism takes place are through endergonic or endothermic reactions in which heat is absorbed as energy by the cell to carry out the procedure of making the larger molecules. The main processes that these anabolic reaction revolve around are photosynthesis, DNA replication, and protein…show more content…
During this process, the Gibbs Free energy (G) cycle plays an important role in the exchanges of free energy depending on the laws of thermodynamics. The second law of thermodynamics states that the state of entropy in the universe will increase and change over time through spontaneous ways (Libretexts 2016). This means that the heat from ones surrounding plus the heat from ones system must be greater than 0 and equal the heat of the universe. This process changes as a constant rate of temperature and pressure are reached in which the equation moves from SUniverse=SSystem+SSurroundings>0to G=H-TS(Gibbs). Through this if the delta G is negative the metabolic processes will continue spontaneously meaning that the reaction is exergonic because it is able to release energy from the cell to its surroundings. And if positive the reactions require energy to take place. The processes of the Gibbs Free energy cycle must be measured under the standard conditions of temperature, concentration, pressure and pH to be correct. In the given equations above the symbols are a representation of enthalpy (H) and entropy (S) in which each one plays an important role in the release of energy from a cell carrying out the metabolic pathways. Enthalpy (H) is known as the sum of internal energy and products of pressure and volume of a thermodynamic
