An enzyme can be defined as anything that increases the rate of chemical reactions by slowing the energy required for the reaction to commence (activation energy). Biological, it can be defined as a protein catalyst inside a cell where most chemical reactions happens. This is achieved when the enzymes speed up the reaction by binding the substrates and maintaining the substrate in a certain orientation that optimize the opportunity of a given chemical reaction to happen, by changing the reactants into products. For any chemical reaction, the substrate material in any enzyme uses many distinct channels for it to for a product. For every path used, there is presence of a transitional element used between the reactants and the ultimate products. Similar to other forms of catalyst, the enzymes are not entirely changed into new things in the chemical reaction they speed up, but they go back to their original condition after the reaction is complete or over. The activation energy is required in the kick off the reaction to form the intermediate product (Vogel & Vogel, 2014). Enzymes have the potential of making it easier for the reactants to get to the transitional condition. The energy taken to reach the transitional condition depends of the easy of reaching that state.
Enzymes are biological chemical agent. Enzymes are inform of folded-shape substrates that bind the locations, and are large size of protein molecules. The binding locations causes the reactants (substrate) to change into the transition state. For reaction catalyzing to occur, a number of the binding locations are precisely located near the substrate of the molecules (Vogel & Vogel, 2014). Alternation of the entire folded shape of the enzyme molecule alter the shape of the binding location. Optimum reaction of the conditions are distinct for every enzyme molecule. The precise surrounding states, particular cofactors, and the correct reactants are linked with the enzyme that are required (Jacobson, 2006). The optimum conditions can be derived from the organism, in which the catalyst is taken, the section of the organism that it operate, and the surrounding condition that the organism survives. The three dimensional shape of a protein determines the potential of the enzyme to function as catalyst.
Catalase is a form of an enzyme that occurs in many living organism that assist to convert hydrogen peroxide to form water and oxygen. Hydrogen peroxide is a constituent of a lipid metabolism (Jacobson, 2006). Is one of the strongest oxidizer that makes it to have free essential formation that are harmful and toxic to cells? However, it very significant for the organism to possess catalase to prevent themselves against free important formation by disintegrating hydrogen peroxide.
